1 Asexual Reproduction Living Environment

2 Mitosis animation:

3 Cut it half Binary Fission = simplest form of asexual reproduction. Parent organism divides into two equal parts. Each daughter cell becomes a new individual. Seen in bacteria and protozoans

4 Binary Fission 2 1 3

5 They Were best buds Budding = Parent organism divides into two unequal parts. The new organism is created as a smaller out growth or bud on the outside of the parent. Buds will break off and live independently or remain attached and form a colony.

6 Yeast – Once the yeast cell reaches a certain size it undergoes mitosis.
Once the genetic material is replicated budding begins. Hydra – Cells on the outside of the parent hydra begin to undergo mitotic division creating a small group of cells. Those cells continue to divide until in a completely new hydra is formed. Can also reproduce sexually.

7 Budding

8 Yeast cell cycle including budding:

9 Can I have some spore? Spore Formation – spores = small specialized cells that contain a nucleus and cytoplasm surrounded by a thick outside wall which protects the spore. Under the right conditions the spore can rise to a new organism. *Found in bacteria, molds, yeast, mushrooms, mosses, ferns and some protozoans.

10 Spore formation

11 Don’t try this at home Regeneration = The ability to re-grow lost or damaged body parts. Hydra, planaria, starfish, and earthworm More complex animals less able to re-grow parts. Crab can re-grow a claw. Some reptiles can re-grow a tail. Most mammals can repair damaged tissue but can not re-grow missing parts.

12 Regeneration
