1. KEY CONCEPT Many organisms reproduce by cell division.

2. Binary fission is similar in function to mitosis.
Asexual reproduction is the creation of genetically identical offspring from a single parent.
Gametes do not join together

3. Binary fission is similar in function to mitosis.
Binary fission produces two daughter cells genetically identical to the parent cell.
Binary fission occurs in prokaryotes.

4. Sexual reproduction is an advantage in changing conditions.
Environment determines what form of reproduction is most advantageous.
Asexual reproduction is an advantage in consistently favorable conditions.
Sexual reproduction is an advantage in changing conditions.

5. Some eukaryotes reproduce through mitosis.
Budding forms a new organism from a small projection growing on the surface of the parent.

Hydra
Yeast

6. Fragmentation is the splitting of the parent into pieces that each grow into a new organism.
Vegetative reproduction forms a new plant from the modification of a stem or underground structure on the parent plant.

7. 2. All organisms can reproduce
Advantages of Asexual Reproduction
1. Can be more efficient
2. All organisms can reproduce
3. Organisms do not need to spend energy/resources on finding a mate

8. All organisms respond the same way to the environment
Disadvantages of Asexual Reproduction
All organisms respond the same way to the environment
May lack the adaptability to survive
No genetic diversity
