1 ASEXUAL REPRODUCTION a result of mitosis

2 reproduction that takes place by mitotic cell divisions
ASEXUAL REPRODUCTION reproduction that takes place by mitotic cell divisions the production of a new organism without the joining of gametes

3 asexual reproduction provides very little genetic variety.

4 FORMS OF ASEXUAL REPRODUCTION
Fission Fragmentation Budding Regeneration Spore

5 Binary fission the division of cells into 2 approx. equal parts
example: ameba

6 fragmentation a form of reproduction caused by the breaking of a colonial organism by a physical disturbance Example: Spirogyra

7 budding a type of asexual reproduction in which portions separate from the parent to form a new individual Examples: yeast & sponges

8 regeneration the ability to replace missing structure; in some organisms, serves as a method of reproduction Examples: planarian, hydra & starfish

9 spore a cell with a hard protective covering Examples: mold, moss &
fungus

10 spore some are carried by wind some have a whip-like structure to swim through water a single spore develops into a new organism
