    TAKING NOTES: 28/9

    ASEXUAL REPRODUCTION : is a method in which offspring emerges from a single parent inheriting its genes, by Regeneration, Vegetative Propagation, Spore Formation, Multiple Fission, Fungi, etc…

    REGENERATION: it carried out by specialised cells which proliferate & create a large number of cells

    VEGETATIVE PROPAGATION : new plants are produced from roots, stems, buds, leafs. The buds produced along the leaf fall and developed new plants (Ex. Bryophylium)

    FRAGMENTATION : a mew organism grows from a fragment of the parent which develops into a mature, fully grown individual

    SPORE FORMATION : a spore germinates and develops into a new organism

    MULTIPLE FISSION : a cell divides into various daughter cells simultaneously

    FUNGI : sporgia’s cells burst open and disperse in the air giving birth to new individuals

    Asexual reproduction:

    When an organism reproduces it makes another of the same species.
    Sexual reproduction combines genes from a mother and a father making a genetically unique organism.
    Other organism reproduce asexually
    In a sexual reproduction all of the genes come from a single parent
    A sexually produce offspring that are genetically identical to the parent
    There are many methods of asexual reproduction, in some one celled organism cell division is a method of asexual reproduction
    Reproduction bacterias cell reproduce through cell division
    The cell makes a copy of dna, then sends to the new bacterial.
    Some bacteria can reproduce as fast as every 20 minutes
    Another method of asexual reproduction is budding.
    Unicellular yeast cells grow new cells off the side of another
    When the cells developed it falls off and a new yeast cell is produced
    Some organism produce offspring by splitting into pieces
    Assian enemy can split down the middle resulting in the production of another individual sexual and asexual reproduction produce offspring however asexual reproduction makes genetically identical offspring
    Sexual reproduction makes genetically unique offspring so try taking a cutting of a plant you will be making another that has the same dna as the parent.

    Asexual vs sexual reproduction

    Purpose of reproduction
    To make sure a species can continue

    Definition
    Reproduction is the process by which an organism produces others of its same kind.

    Sexual reproduction requires two parents: each of their body cell contains 100% of their dna in the nucleus

    Sex cells gametes each sex cell contains 50% of the needed in a body cell

    Fertilization union of male and female sex cells
    Fertilization can happen internally . As in humans, or externally, as in the fish

    Cell division mitosis the process by which a parent cell divides into two or more daughter cells

    Offspring the offspring has inherited 50% of the dna from its mother and 50% of its dna from the father
    This offspring has a random mix of genes that will make it slightly different from its brother sister mother and father

    Asexual reproduction
    Asexual reproduction results in offspring that are genetically identical to the parent organism
    This means that 100% of the dna found in the offspring of asexual reproduction is the same as the one parent they inherited it from.

    ASEXUAL REPRODUCTION = a method in which offspring emerges from a single parent inheriting its genes, by Regeneration, Vegetative Propagation, Spore Formation, Multiple Fission, Fungi, etc…

    REGENERATION = carried out by specialised cells which proliferate & create a large number of cells

    VEGETATIVE PROPAGATION = new plants are produced from roots, stems, buds, leafs. The buds produced along the leaf fall and developed new plants (Ex. Bryophylium)

  4. Anouk LAF dijo:

    TAKING NOTES: 7/9

    Asexual Reproduction = only 1 parent which creates identical offspring
    Sexual Reproduction = 2 parents

    REPRODUCTION = The process by which organisms produce more offspring, identical or similar to the parent, of its same kind. These makes sure species can continue.

    SEXUAL REPRODUCTION: The production of a new organism by the fusion female & male gametes by the process of fertilisation

    ASEXUAL REPRODUCTION: The production of a new organism without the fertilisation of gametes which creates genetically identical offspring that can be produced by Binary Fission, Budding, Fragmentation, etc…

    BINARY FISSION: A fast & effective process esencial for cell division, similar to mitosis, by duplicating its DNA and diving into 2 different organisms. (Bacteria – Fungi – Algeae)

    BUDDING: A slow but effective process in which a tiny part appears from an organism (bud), that later grows and falls crape aging a separate organism.(Hydra)

    FRAGMENTATION: A different way of asexual reproduction in which an organisms splits into fragments/pieces, which can each later grow and became separate organism

    Bullet points: Asexual Reproduction 27/9

    -Asexual reproduction: process through which an organism produces other organisms without participation of more than one parent. Offsprings:identical to parent
    -Makes organisms identical to another with the same genetic material: clones
    -For example: bacteria
    -Prokaryotic cells reproduce by this process
    -Sometimes eukaryotic cells reproduce like this
    -Produces offspring with same genetic material
    -When organisms reproduces, makes offspring of same species
    -Asexual reproduction-genes from same parent
    -Bacteria reproduced through cell division
    -Types of asexual reproduction:
    .Bipartition/Binary Fission: spontaneously, cells who do this breaks into two clones, -offspring with same DNA. Fast as 20 minutes
    .Budding: when a tiny part of the organism grows into a separate organism.
    .Fragmentation:Splitting into pieces. This pieces will grow and form different organisms
    .Vegetation Propagation:when you take a part of the plant and you re-plant it. It will start to grow. The reproduction takes place through the vegetative buds of the plant.
    .Multiple Fission: when an organism simultaneously separates into many daughter cells
    .Regeneration: when an organism loses a part of it’s body a new organism will grow from that part. Moreover, the lost part in the “main body” will also regenerate.
    .Spore Formation: When a spore, an asexual reproductive body, starts to grow and develops into a new individual

    There are many methods of asexual reproduction
    1)Binary fission
    2)Multiple fission: Some single-celled organisms divide into many daughter cells simultaneously. Plasmodium reproduce through this method.
    3) Regeneration: Simple organisms are cut into many pieces. Each piece grows in a new, separate and complete organism. This process is carried out by specialized cells which proliferate and make a lot of cells, as planaria.
    4) Vegetative propagation: New plants are produced from roots, stem, leaves and bud. It is named like this because the reproduction takes place through the vegetative parts of a plant. Therefore, the plant Bryophyllum is another example of this process. The buds that have been produced by this plant fall on the soil and develop into new plants. Potatoes are another example, if a potato is cut into small pieces along its eyes or scars, then you bury them in the soil and water them properly a new potato plant will grow.
    5)Budding
    6) Spore formation: Spores are asexual reproduction bodies, each of these is covered by a hard protective court to prevent unfavorable conditions, as high temperature or low humidity. These spores germinate and develops into a new individual. Fungi reproduce by this method.

    There are many ways of reproduction. Here are some examples:
    – Multiple Fision, it is like binary fision but but dividing in many daugther cells simultaneously and it is made by single-cellular organisms.
    -Regeneration, organisms simple divided into many number of pieces creating a new organism.
    – Spore Formation, spores are asexual reproductive body, they germinates and develops into a new individual.

    Asexual and sexual reproduction
    Reproduction is the formation of new organisms. There are two types of reproduction.
    The porous of the the reproduction is to make sure a species can continue.
    Each species reproduces in a different way. However, there are only two types – asexual reproduction, and sexual reproduction.

    ASEXUAL:
    Asexual= 1 person (is the process through which one organism produces new living organisms without the participation of another organism. The offspring are identical of their parents).
    The production of a new organism without fertilisation to gametes (one parent produce one identical daughter, she replicates the DNA)
    Examples of asexual reproduction:
    Partitions/Binary Fission: Is the reproduction that does the bacteria, the bacteria is duplicated with the same DNA.
    An example of this process is the paramecium when the process begins with the division of the nucleus, then they are divided into two organisms the each of them has an equal nucleus. ( pluricelulares)
    Another example for the cell division is when bacteria and protozoa split into two equal halves. (unicelular)
    Multiple fission: Single cell organisms such as the Malaria Parasite (Plasmodium) it is divided into many daughter cells simultaneously.
    Regeneration: Animals like Planaria can be cut into many number of pieces. And each piece grows into a complete organism.
    Budding: This kind of reproduction is made by some plants. They are produced by the yeast. The bud of the plant is produced in the parent, but when the daughter grows, she will be separated and it will be a new organism.
    An example is the Bryophyllum that from it lives new plants can develop after coming in contact with soil then this new plants can separately from the live and can develop into a complete plant on the ground.
    Splatting: It is made by some plants. The plant is separated into two parts with the same DNA. The organisms are split on fragments and then they have the capacity to became a new organism and it is also separated from her parent.
    Spore formation: Is when a spore germinates and develops into a new individual. One example is the Fungi, and one of it types is the Aspergillus. The blobs that can be seen growing on the surface of a bread are called Sporangia which contains spores hata eventually opened and dispersed in the air to give birth a new individual.
    Organisms which contain the same genetic material, are called clones.
    All the mistakes that has the cell parent will go on to the daughter cell. This means that the daughter cell is a clone of the parent cell.
    Vegetative Propagation: It’s a type of reproduction in plants. On example is the potato. In potatoes if it is cut into small pieces along with the eye, buried in the soil and water properly a new potato grows.
    An example of a cell division in the shallot bulb is:
    A bulb is an underground bud. The shoot (stem) is very short and never grows above the ground. The leaves are thick and fleshy, because they contain stored food. They are white because being underground they cannot photosynthesis and they not nerd chlorophyll.
    In spring the main shoot and side shoot will grow above the ground, that will turn into green and photosynthesis.
    Food from the photosynthesising shoots is used to produce a daughter bulb.
    Some animals can also be reproduce asexually and form clones.
    After this a group of shallot bulbs are form.
    The only kind of the organisms who can do the reproduction in a asexual way is the Prokaryotic organisms for example ten bacteria.
    Some of the eukaryotic who has a single-celled can also do the reproduction in the axecual way.
    Binary Fission is the division of a bacteria (microscope). This process is used in the clones.
    As you know mitosi help the unicelular organismo to reproduce (mitosis is the responsible to reproduce in the unicellular organisms.

    Reproduction.
    Purpose: make sure a species can continue
    Definition: Process by which an organism reproduces others of the same kind.
    Asexual Reproduction:
    A.R result in offspring that is identical that are genetically identical to the organism.
    This means a that the DNA found in both is 100% identical.

    In unicellular organisms which use asexual reproduction can do so very rapidly simply by dividing into two equal halves. This is called binary fission.
    Plants can reproduce by asexual rep. This is called vegetable propagation.
    Bidding, bidding is when a tiny part of the organism grows into a separated organism.
    Fragmentation is another form of asexual rep. The organism is split into fragments or pieces, the pieces can grow and become a separated organism.
    Cell division:
    In multicellular organisms it is responsible for growth and repair.
    In unicellular organisms it is responsible for reproduction.

    Asexual Reproduction:

    The porpouse of asexual reproduction is to make sure that species continue reproducting.
    Asexual reproduction consist in 1 parent cell that produces a daughter cell with identical gentical materia and with the same DNA.
    The asexual reproduction have advantages and disadvantages, the advantages that this have is that with the asexual reproduction, the organisms reproduct very fast. And the disadvantage that the asexual reproduction have is that there are not genetic variety, all the organisms are totally identical to the parent cell.
    There are different ways of reproducting asexualy:
    Binary fission consists in cell division, the cell splits into two.
    Budding, is a way in which a tiny part of an organism grows into a separate organism.
    Fragmentation consists in which the organism splits into fragments.
    And the last is the vegetation. The plants reproduce in this way.

    These are my note of the second video we have seen in class:

    – Asexual reproduction results an offspring that is genetically identical to the parent cell.
    – The offspring have exactly the same DNA than the parent cell. For example, if the parent cell can’ t adapt to temperature the offspring wouldn’t adapt either. This is not very good because any problem that the parent cell have, the offspring have it too.
    – With asexual reproduction we obtain clones, the parent and the daughter cell are identical to each other.
    – BINARY FISSION. Binary fission happens when unicellular organisms they divide into two. An example of an organism that reproduce through binary fission is bacteria.
    – VEGETATIVE PROPAGATION. This is the way in which many plants reproduce using asexual reproduction.
    – BUDDING. Budding is when a very tiny part of the organism grows into a separate organism. An example of an organism that reproduce through budding is the yeast.
    – FRAGMENTATION. In fragmentation living organisms split into things called “ fragments or pieces”. The pieces can grow and become another organism.

    We have studied many four types of asexual reproduction, but there are more ways in which asexual reproductors organisms can reproduce. Types of asexual reproduction:

    – Regeneration: Some animals like planaria can be cut into many pieces and each of them can grow into a new complete organism.
    – Spore Formation: This is the type of asexual reproduction that spores use. Spores are asexual reproductive bodies that have a hard protected court that helps it to resist to high temperatures or low humidity. These spores reproduct and develops into a new individual.
    – Multiple Fission: This process is similar to Binary Fission, but in this case, an organism divides into more organisms that later are going grow and reproduct by themselves.

    – Regeneration is the process in which specialised organism lose a part of their bodies which start to grow and end up forming and identical to their parents organism.

    – Multiple fission is the method in which the organism divides spontaneously into multiples and identical organisms.

    – The process of spore formation consists of a spore, which is an asexual reproductive body, germinates and develops into a new individual one. Moreover, the blobs that can be seen growing in the surface are called sporangia which contain cells or spores that burst open and disperse in the air to create the new individual organisms.

    – The process in which new plants are produced from roots, stems, leaves and buds is called Vegetative propagation. An example of this process is potato, if it is cut into very thin pieces, and is buried and watered properly, a new potato plant will grow from it.

    Multiple Fission: multiple fission is a method of asexual reproduction in which an organism splits into many identical parts. Later these parts can become a new organism.
    Regeneration: regeneration is a method of asexual reproduction in which an organism can be cut into any pieces that later become a complete organism. This process is carried out by specialized cells which proliferate and create large number of cells.
    Vegetative Propagation: vegetative propagation is a method of asexual reproduction in which new plants are produced from roots, stems, leaves and buds. This is process is called “vegetative propagation” because the reproduction takes place in the vegetative parts of the plant.
    Spore Formation: spore formation is a method of asexual reproduction. Spores are a sexual reproductive bodies. Each spore is covered by a hard protective court. The spore germinates and develops into a new individual. An example is fungi.

    -Vegetative Propagation; done by plants in which new plants are produced from roots, stems, leaves and buds. It takes place through the vegetative parts of the plant, and that’s the reason for its name. An example of vegetative propagation comes across in the case of a plant called Bryophyllum, where the buds produced in the notches along its leaf fall on the soil and develop into new plants. Another example is the potato.
    -Spore formation;spores are asexual reproductive bodies, each of them is covered by a hard protective court to withstand unfavorable conditions such as high temperature and low humidity. A spore germinates and develops into a new individual. An example of this is fungi.

    Reproduction in plants

    Reproduction: process by which new organisms are produced.

    There are 2 methods of Reproduction depending on:
    1 parent is involved
    Called asexual reproduction
    Offspring identical
    2 parents are Involved
    Called sexual reproduction

    Asexual reproduction
    Process through which one organism produce other, without the participation of other living being.
    1 parent involved
    Identical to their parent
    Same genetic materials than their parent
    Clones: Identical to another organism, same genetic material.
    When the conditions of the environment are constant, asexual reproduction is fast/effective.
    The parent organism reproduce itself (do not need another compatible organism)
    Asexual reproduction → bacterias, prokaryotic organisms, single-celled eukaryotic organisms, many fungi and multicellular algae, some animals and plants (when environmental conditions are not favourable) but If conditions are good and they reproduce sexually it is better for the progress of the species.

    Many forms of asexual reproduction:
    -Binary fisson
    -Unicellular organisms reproduce by dividing into two equal halves.

    Budding
    The organism generates a bud which separates itself and become another identical being.
    Example: Hydra
    Fragmentation
    The organism splits into fragments. The pieces can each grow and become a separate organism.
    Spore formation

    Sexual reproduction
    Two living beings that belong to the same specie produce new organisms.
    (Two compatible organisms)
    2 parents Involved
    The Descendents are a mix of the characteristics of the 2 parents.

    • Regeneration: this happens when organisms lose part of their body and that part that the organism loses forms a new organism.
    • Multiple Fission: the organism is divided into many parts.
    • Advanteges and Disadvantages of Asexual reproduction:
    – ADVANTEGES: the process is shorter and quicker no energy is lost.
    – DISADVANTEGES: there is no genetic variation unless a change occurs.

    -Organisms can reproduce sexually or asexually.
    -Some organisms reproduce sexually, combined genes from the parents making a genetically unique offsprings.
    -Asexual reproduction: the genes come from a single parent which makes genetically identical offsprings to the parent, with the same DNA.
    -Binary(two) Fission(separation)- bacteria. They reproduce themselves by asexual reproduction, they split into two.
    Budding- yeast. An organism grows on top of another organism.

    -Asexual reproduction: process by which 1 organism produces new organisms without the participation of another organism.
    The offspring are identical copies of the parent organism. The parents cell and the offsprings cells contain the same genetic material. This organisms are called CLONES, because they contain the exact same gm. When the environmental conditions are constant, this reproduction is fast and effective because the parent doesn’t need to find a compatible organism to reproduce and because if the parent is suitably adapted to the environment, the offspring will be adapted too, as they are clones. Asexual reproduction is the only way by which bacteria and other prokaryotic organisms. The asexual reproduction is common among single-celled eukaryotic organisms, like protozoa, yeast and single-celled algae. Many fungi and multicellular algae, adopt this form of reproduction in certain circumstances. If conditions are good they can, If it isn’t, they can’t.
    -Asexual reproduction; many forms;
    •Bipartition/Binary fission(the organism spontaneously divides into two identical ones, for example bacteria).
    •Budding (the organism spontaneously generates a bud which ends up separating and becoming another identical individual, for example hydra), fragmentation, spore formation.
    -Sexual reproduction; 2 compatible organism(same species) cooperates to produce new organisms. The descendant genes are a mix of the characteristics of both parents.

    •Budding: This kind of reproduction is made by some plants. They are produced by the yeast. The bud of the plant is produced in the parent, but when the daughter grows, she will be separated and it will be a new organism.
    •Splatting: It is made by some plants. The plant is separated into two parts with the same DNA.
    •Organisms which contain the same genetic material, are called clones.
    •The only kind of the organisms who can do the reproduction in a asexual way is the Prokaryotic organisms for example ten bacteria.
    •Some of the eukaryotic who has a single-celled can also do the reproduction in the axecual way.
    Binary Fission is the division of a bacteria (microscope). This process is used in the clones.

    SEXUAL:
    •Sexual= 2 persons (two compatible organisms of the same species cooperate to produce new living organisms).
    •The reproduction of a new organism when two gametes fuse together though the process of fertilisation.

    7/9 Asexual Reproduction

    – In asexual reproduction we have one parent cell which produces another cell with identical DNA.
    – In asexual reproduction all the genes come from a single parent.
    – Organisms reproduce themselves by asexual reproduction.
    -Many methods of asexual reproduction:
    Binary Fission= they split into two.
    Budding= Budding is a type of asexual reproduction that is a process by which a bud comes out from the parent cell.
    – Asexual reproduction produce genetically identical offspring.

    Notes for asexual reproduction

    Bacterias reproduce asexualy by Binary fission. This means that they simply split into two. There is another type of asexual reproduction called budding. This consists of a new organism that appears from something.

    In asexual reproduction all genes from only one parent. The offspring produce is genetically identical to the parent. These are all the types of asexual reproduction, 1)Bipartition 2) Budding 3) Cutting

    Asexual reproduction:

    – It is the Process by which one organism produces a new living organism without the participation of another. The new organism is yes or yes identical. Both the parent’s cells and offspring’s cells contain the same genetic material. Whenever an organism is an identical from it’s parent having the same genetic material are called clones. When environment is constant asexual reproduction is fast and effective because they don’t have to find a compatible organism and because if they are suitable for it, the offspring will also be. The only form that bacteria and other prokaryotic organisms is by reproduction. This type of reproduction is common for single-celled eukaryotic organisms such as protozoa, single-celled algae and yeast. Many fungi and multicellular algae adopt this form of reproduction in certain circumstances.There exist many forms of asexual reproduction: Bipartition (Divides spontaneously into two like bacteria), Budding (Organism spontaneously creates a bud which ends up separating and becoming another identical individual like Hydra),

    Taking notes: Asexual Reproduction

    Video 1
    • In Asexual reproduction 1 parent cell produces a daughter cell with identical DNA. Same genetic material.
    • Bacteria: they reproduce asexually. Also they reproduce themselves and very fast. They reproduce by binary fission= cell division.
    • Plants reproduce asexually and by budding.
    • All of the genes comes from a single parent
    • Asexual reproduction makes genetically identical offspring to the parent cell.

    Porpouse of reproduction: to make sure that species continues.

    Reproduction
    organisms create new living ones
    the process can be asexual or sexual
    sexual: two organisms create new living organisims.
    asexual: an organism is created through a single parent with the same genetic material.

    Asexual reproduction

    all the genes come from a single parent
    example :bacteria
    eukaryotic cells can reproduce this way
    produces offspring with identical DNA.
    prokaryotic cells reproduce this way
    through cell division bacteria is reproduced
    offspring of same specie is created when 2 organisms reproduce.

    Types of asexual reproduction

    Budding:

    Bipartition or binary fission: cells which breaks into clones spontaneously
    process by which a bud cames out from a parent cell and grow in order to separate from the parent.

  31. Belen Brito Peret dijo:

    -Bacteria reproduce asexualy and the way they reproduce is call Binary fission.
    -Cutting is an artificial way to reproduce, the gardenes do it.
    -Sexual reproduction combine genes.
    -All the genes come of a single parent
    -Identical of the parent
    -Cell makes DNA.
    – Bacteria takes 20 minutes to reproduction
    -Divisions is a method of asexual reproduction.
    -Budding unicelular.
    -Offpring is the resultion in another individual, (the decendens), what ever is born. Usually is not for bacteria. Type of a sexual reproduction of a parent cell
    -new cells of side of another
