sexual and reproduction & meiosis/ asexual reproduction test

__________ is a form of asexual reproduction in which offspring grow from a part of a parent plant.

Vegetative reproduction

In _______, one parent organism produces offspring without meiosis and fertilization.

asexual reproduction

Diploid cells - organisms that reproduce sexually make what two kinds of cells

body and sex cells

in___ a new organism grows on the body of its parent by mitosis and cell division

buding

during meiosis II, _____________ cells separate to produce four haploid cells.

chromatids

If a zygote has too many or too few ______ , It will not develop properly.

chromosomes

Meiosis forms sex cells with the correct haploid number of _____. This maintains the correct _____ number of chromosomes in organisms when sex cells join.

chromosomes, joint

______ is a type of asexual reproduction developed by scientists and performed in laboratories. It produces identical individuals from a cell or form a cluster of cells taken from a multicellular organism

cloning

During fission, DNA is ____ and the cell splits to form two identical offspring. The original cell no longer exists.

copied

In mitotic cell division, a type of asexual reproduction, an organism forms two offspring through mitosis and _____

cytokinesis

meiosis involves two divisions of the nucleus and the _______. These divisions, known as meiosis I and meiosis II, result in four haploid cells.

cytoplasm

body cells are called ?, it means have what

diploid, pairs of chromosomes

Another disadvantage is that searching for a mate takes time and energy and might expose individuals to predators, ____, or harsh environmental conditions.

diseases

what is the female sex cell and where does it form

egg, ovary

genetic varioation gives individuals within a population slight differences that might be an advantage if the ________ changes

enviornment

Many unicellular ____ reproduce by mitotic cell division.

eukaryotes

during what process do an egg and sperm join together

fertilization

cell division in prokaryotes us known as _____

fission

Meiosis creates genetic variation by producing ______ cells

haploid

When sex cells are ______; they have only one chromosome from each pair of chromosomes

haploid

_______ are pairs of chromosomes that have genes for the same traits arranged in the same order

homologous chromosomes

Because the offspring of asexual reproduction inherit all their DNA from one parent, they are genetically ______ to each other and their parent.

identical

during ______, the reproductive cell grow and duplicates its chromosomes

interphase

In budding, when the bud becomes _______, it can break form the parent and live on its own.

large enough

asexual reproduction enables organisms to reproduce without a(n)_____

mate

during ______, a reproductive cell and its nucleus divide twice and produce four cells- two pairs of identical haploid cells.

meiosis

in ______; one diploid cell divides and makes four haploid cells.

meiosis

during ___and cell division, a body cell and its nucleus divide once and produce two identical cells

mitosis

genetic changes, called _______ can occur and then be passed to offspring ; this can affect the offspring's ability to survive

mutations

after meiosis 1, the two cells formed during this stage go through a second division of the _______ and cytoplasm called meiosis II.

nucleus

different organisms have different _______ of chromosomes

numbers

Regeneration of body parts is not reproduction because _____ are not produced

offspring

asexual reproduction also enables some organisms t rapidly produce a large number of______

offspring

sexual reproduction produces ______ that have a new combination of DNA

offspring

asexual reproduction produces offspring that are genetically identical to each other and to their _____.

parent

Many animals can _____ damaged or lost body parts.

regenerate

_______ occurs when an offspring grows from a piece of its parent

regeneration

sea stars, sea urchins, sea cucumbers, and planarians can _________ through regeneration

reproduce

______ breeding has been used to develop desirable traits in plants and animals

selective

during meiosis 1, each pair of duplicated homologous chromosomes _________

seperate

one disadvantage of sexual reproduction is that organisms have to grow and develop until they are mature enough to produce ______ cells

sex

what is the male sex cell and where does it form

sperm, testis

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 scientists can use a meristem to make a copy of a plant with desirable traits.

tissue culture

Asexual reproduction produces offspring that are genetically identical and results in minimal genetic _____ within a population.

variation

The offspring produced by sexual reporduction results in genetic _______ among individuals.

variation

what is the new cell that forms

zygote

because all of a clone's ________ come from one parent, the clone is genetic copy of its parent.

DNA

What is sexual reproduction?

Sexual reproduction produces an offspring when genetic materials from two different sex cells combine.
