KEY CONCEPT Many organisms reproduce by cell division.

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 parent cell DNA duplicates cell begins to divide daughter cells

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. parent cell DNA duplicates cell begins to divide daughter cells

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.

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

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.

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 parent cell DNA duplicates cell begins to divide daughter cells

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 parent cell DNA duplicates cell begins to divide daughter cells
