1. Asexual Reproduction

2. What is Asexual Reproduction?
Involves only ONE parent
All offspring are genetically identical to each other and the parent!
Can produce large numbers of offspring very rapidly!

3. Binary Fission… basically mitosis!
Simplest form of asexual reproduction
Parent divides it’s nucleus and cytoplasm into two equal parts and splits into two cells that are equal in size
No parent cell remains
Occurs in unicellular organisms like amoebas, paramecium, bacteria, etc.

5. Budding Parent divides into two unequal parts
New individuals grow out of the body of the parent
Parent remains and parent and offspring are not the same size
Occurs in yeast, hydra, sponges, and some worms

7. Spore Formation
Small, sometimes microscopic, cells called spores are formed (usually in large amounts)
Spores contain cytoplasm and genetic information
Surrounded by a tough outer coat that protects them from unfavorable environmental conditions
When conditions are good the spore develops into a new organism
Ex: bacteria, yeast, molds, mushrooms, ferns

9. Regeneration Ability of an organism to re- grow lost body parts
Involves the development of a new organism from a part of the original organism
Ex: hydra, planaria, sea stars, earthworms

11. Vegetative Propagation
Asexual reproduction in plants
Occurs when parts of the parent plant are used to grow a completely new plant
Occurs both naturally and artificially
