1
Many organisms reproduce by cell division.
2
Sexual Reproduction- joining of an egg and sperm cell, one from each of two parents.
Offspring are genetically unique Have a mixture of genes from both parents Asexual Reproduction- creation of offspring from a single parent and does not involve the joining of gametes. Offspring are genetically identical to each other and the single parent.
3
Most prokaryotes reproduce through binary fission.
Binary fission- asexual reproduction of a single celled organism by division into two daughter cells genetically identical to the parent cell. parent cell DNA duplicates cell begins to divide daughter cells
4
Mitotic Reproduction Some eukaryotes reproduce through mitosis. - Usually simple plants and animals There are three types: Budding Fragmentation Vegetative Reproduction
5
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.
7
Vegetative Reproduction forms a new plant from the modification of a stem or underground structure on the parent plant.
8
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.
9
What are other advantages for asexual reproduction?
All organisms can potentially reproduce. - Male and female have offspring Don’t have to look for a mate. - takes time, energy need specific structures, signals, and behaviors
