Asexual Reproduction

Asexual Reproduction

Poll

Which of the following has to do with asexual reproduction

• offspring are identical to the parents

• offspring look similar to the parents

• offspring have half of each parents DNA

• Takes time and energy

Asexual reproduction

• One parent organism produces offspring without meiosis and fertilization

• Offspring are genetically identical to each other and the parent

Multiple Choice

I asexual reproduction how many parents are there

• 1

• 2

• 4

Multiple Choice

In asexual reproduction offspring inherit half of the DNA from their parents

• True

• False

Multiple Choice

Asexual reproduction does not use the process of meiosis

• True

• False

Types of Asexual Reproduction

• Fission

• Mitotic Cell Division

• Budding

• Animal Regeneration

• Vegetative Reproduction

• Cloning

Fission

• Cell division in prokaryotes That form two genetically identical cells.

• This is more simple than mitosis

• DNA molecules are copied and the cell elongates

• The center pinches inward

• Then the cell splits completely.

Prokaryote

A microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and cyanobacteria.

Eukaryote

contains membrane-bound organelles such as a nucleus, mitochondria, and an endoplasmic reticulum. Organisms based on the eukaryotic cell include protozoa, fungi, plants, and animals. These organisms are grouped into the biological domain Eukaryota.

Multiple Choice

Prokaryotes divide through a process called mitosis

• True

• False

Mitotic Cell Division

Many unicellular eukaryotes reproduce by mitotic cell division.

In this cell division an organism forms two offspring through the process of mitosis.

Multiple Choice

Some individuals reproduce asexually through a process of meiosis

• True

• False

Budding

• A new organism grows by mitosis and cell division on the body of its parent

• The bud or offspring is genetically identical to the parent

• When a bud becomes large enough it can break off and live on its own

• In some cases it will remain attached and form a colony

Multiple Choice

Buds are genetical identical to their parents

• True

• False

Animal Regeneration

• Another type of asexual reproduction

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

• This can vary among animals

Vegetative Reproduction

• Is a form of asexual reproduction in which offspring grow from a part of a parent plant

• Usually involves roots, the stem and leaves

• you can take a bud from one tree and put it on another this is called grafting

Multiple Choice

Cutting of a bud from a tree and putting it on another is called

• gluing

• growth

• grafting

Cloning

• Is a type of asexual reproduction performed in a lab that produce identical individuals from a cell or from a cluster of cells taken from a multicellular organism

Multiple Choice

Cloning takes place where

• your house

• in the wild

• in a lab

Advantages of asexual reproduction

• Offspring get all of the genes of the parent

• Reproduce rapidly

• No need for a mate

• large number of offspring

• Ability to colonize

Disadvantage of asexual reproduction

• less chance of survival of a population

• undesirable mutations will be passed on to offspring.
