Asexual reproduction lesson 2 study set💜
Because the offspring of asexual reproduction inherit all their DNA from 1 parent, they are genetically ________ to each other and their parent.
Identical
Asexual reproduction produces offspring that are genetically identical to each other and to their _______. This results in minimal genetic _______ w/in a population.
Parent; variation
Asexual reproduction in which a new organism grows from a piece of its parent
Reseneration
form of sexual reproduction in which offspring grow from a part of a parent plant is called vegetative reproduction
True
Explain: why the offspring of asexual reproduction are genetically identical to each other and to their parent
the offspring are all clones of the original parent
Identify: the 2 main advantages for organisms that reproduce asexually
the population can increase rapidly when the conditions are favorable only one parent is needed
Define: asexual reproduction
type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes
Because all of a clone's ______ come from one parent, the clone is a genetic copy of its parent.
Chromosomes
______ is the process of making identical individuals.
Cloning
_____ is a type of asexual reproduction developed by scientists and performed in labs. It produces_____ individuals from a cell or from a cluster of cells taken from a multicellular organism.
Cloning; identical
During fission, DNA is________ and the cell splits to form 2 identical offspring. The original cell no longer exists.
Copied
The process of growing living tissue in a lab
Culture
Many unicellular ______ reproduce by mitotic cell division. In this type of asexual reproduction, an organism forms 2 offspring through mitosis and ______.
Eukaryotes; division
A disadvantage of sexual reproduction is that the organisms can reproduce w/out using time and energy to find a mate
False; an advantage
cell division in prokaryotes is known as mitotic cell division
False; fission
Cloning produces identical individuals from a cell or cluster of cells taken from a unicellular organism
False; multicellular
Some animals have been cloned using the cytoplasm from a cell in one parent
False; nucleus
Cell division in prokaryotes
Fission
cell division in prokaryotes is known as ________.
Fission
Many animals can _______ damaged or lost body parts. This is not reproduction; ______ are not produced.
Regenerate; new individuals
_____ occurs when an offspring grows from a piece of its parent.
Regeneration
Sea stars, sea urchins, sea cucumbers, and planarians can _______ through regeneration.
Reproduce
Genetic variation is important because it can give organisms a better chance of _____ if the environment changes.
Surviving
Using a cloning method called______, plant growers and scientist can use a meristem to make a copy of a plant w/ desirable traits.
Tissue culture
A hydra grows a new hydra on its body using a form of asexual reproduction called budding
True
In all types of sexual reproduction, offspring are produced by one parent organism.
True
Many unicellular eukaryotes reproduce by dividing into 2 offspring through mitosis & cell division. This form of reproduction is known as mitotic cell division
True
Meiosis and fertilization are not part of asexual reproduction.
True
Some animals can grow a new limb in a process called regeneration
True
________ is a form of asexual reproduction in which offspring grow from a parent plant.
Vegatative reproduction
Asexual reproduction by plants
Vegetatative reproduction
Which type of asexual reproduction in plants is most similar to animal regneration?
Vegetative reproduction is most similar toanimal regeneration because in both types of a sexual reproduction a new organism grows from a part of the parent organism
Why is growing a new plant from cloning different from vegetative reproduction?
A tissue culture is done by humans. It does not occur in nature.Vegetative reproduction occurs in nature.
In _______, one parent organism produces offspring w/out meiosis and fertilization.
Asexual reproduction
The prodution of offspring by one parent w/out meiosis & fertilzation
Asexual reproduction
A type of asexual reproduction in which a new organism grows on the body of the parent organism
Budding
In_______, a new organism grows on the body of its parent by mitosis and cell division. When the bud becomes ______ enough, it can break from the parent and live on its own.
Budding; large
How has the definition of cloning changed from the past to today?
In the past, cloning described any process that produced genetically identical offspring.Today, cloning usually refers to a type of a sexual reproduction developed by scientist stand performed in laboratories
Asexual reproduction enables organisms to reproduce w/out a(n) ______.
Mate
Genetic changes, called _________, can occur and then be passed to offspring; this can affect the offspring's ability to survive.
Mutations
If a sea star grows a new arm, is the regeneration a form of asexual reproduction?
No; a new organism was not produced
Asexual reproduction also enables some organisms to rapidly produce a large number of ____.
Offspring
Possibillity
Potential
List: 6 types of asexual reproduction
binary fission, budding, vegetative propagation, spore formation, fragmentation, parthenogenesis, and apomixis
Explain: how plant cloning is useful for farmers and scientists
cloned to produce identical plants quickly and economically
