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
