2. Asexual reproduction only needs _____ parent!!!!

3. Binary Fission One cell becomes two. In Prokaryotic organisms, such as bacteria its how they Reproduce !!! There entire bodies are only the size of one cell. If we could reproduce this way, Mr. Sergent could simply split and make two Mr. Sergent’s. Would that not be great!!!!

4. Binary Fission is fast!!!! Bacteria cells undergo binary fission! In a single night one can become billions. http://www.youtube.com/watch?v=gEwzDydciWc&NR= 1

5. Our bodies undergo Binary Fission as well. The Eukaryotic cells in our body,SOMATIC cells divide through Mitosis which is a form of “BINARY FISSION” http://www.youtube.com/watch?v=nPG6480RQo0&fe ature=related http://www.youtube.com/watch?v=nPG6480RQo0&fe ature=related

6. Binary Fission in Bacteria versus Binary Fission in Eukaryotic cells. http://www.youtube.com/watch?v=nPG6480RQo0&fe ature=related http://www.youtube.com/watch?v=nPG6480RQo0&fe ature=related 1. Which divides faster, bacteria cells or our cells? 2. What are two advantages of being able to reproduce like a bacteria cell? 3. What are some disadvantages of being able to reproduce like a bacteria?

7. “Regeneration” Allows organisms to grow back body parts! Some organisms like planarians that are cut into sections will grow back into two organisms. http://www.youtube.com/watch?v=JrcDLew55tU http://www.youtube.com/watch?v=4exOh6swPp8&fea ture=related http://www.youtube.com/watch?v=4exOh6swPp8&fea ture=related http://www.youtube.com/watch?v=vXN_5SPBPtM&N R=1 http://www.youtube.com/watch?v=vXN_5SPBPtM&N R=1

8. Asexual reproduction vegetative propagation 3 methods of vegetative propagtaion -tubers -bulbs -runners

9. Tubers Tubers are underground food stores which stores food over the winter and provides a new plant with food until it can make its own. Food made by the new plant is sent to make new tubers. Thereby reproducing itself. Examples: potato, artichoke, yam, cassava, water chestnut, arrowroot Taro- Japanese potato

10. Bulbs E.g. daffodils, lilies

11. Runners Runners are side shoots which grow out from the parent plant. Buds form at points along the runner and eventually these buds form roots and grow into new plants. Examples: spider plant (Anthericum), strawberry ( Fragaria x ananassa)

12. Cutting They can be placed in moist soil or water (and sometimes dipped in rooting powder). Cuttings are small pieces of stem with some leaves attached, the new plant grows from this.

13. Grafting A cut stem of one plant (with good flower or fruit growth) (the graft) is taken and firmly attached to the rootstock of another plant (which has a strong, established root system) (the stock). Examples- roses, fruit trees

14. I can “Learning Check” What are three ways that a plant can go through vegetative propagation? What are two ways that a plant can go through artificial vegetative propagation?

15. Budding When an organism reproduces by growing an identical copy on the outside of its body.

16. Budding Hydra http://www.youtube.com/watch?v=489CSop00sY

17. Parthenogenesis The development of eggs that have not been fertilized.

19. I can “Learning Check” What are the advantages of budding? What are the advantages of parthogenesis? What organisms may undergo budding? What organisms may undergo parthogensis?
