1. Cell Division and Asexual Reproduction

2. Two Types of Reproduction
Asexual
Only one parent
Offspring are identical to parent
Sexual
Two parents (egg cell and sperm cell)

3. Types of Asexual Reproduction
Binary Fission
Budding
Vegetative Reproduction
Fragmentation
Spore Formation

4. Characteristics of Asexual Reproduction
Only one organism is needed to reproduce
All the offspring are genetically identical to each other and to the parent organism
A single organism can produce large numbers of offspring

5. Binary Fission
Parent undergoes cell division to produce two genetically identical daughter cells or offspring
Example: Bacteria

6. Binary Fission
Allows for rapid population growth under ideal conditions
Bacteria can double population every 20 mins

7. Budding Offspring begin as a small growth on the parent
Bud keeps growing (cell division) and eventually breaks off from parent
Example: Yeast

8. Vegetative Reproduction
Plants that reproduce asexually
Strawberries send out “runners” that can form into new plants

9. Fragmentation
Small part of an animal breaks off and grows into a new organism
Example: Sea Star

10. Fragmentation
Parent can regrow lost body part
Called “Regeneration”

11. Spore Formation Reproduction via forming large numbers of spores
Spores = similar to seeds

12. Bill Nye: Cloning Video

13. Cloning Activity - Groups of 3
You and your group are in charge of the Science and Technology branch of the Government of Canada
List out the pros and cons of cloning (human, animals, etc.)
State your stance on cloning (fully agree on all fronts? Support only animal cloning?)
Submit regulations (“we will allow cloning under these circumstances”)

14. Review Questions To help study for the test
Will not be collected, but if you do these questions, it will definitely help
