Sexual and Asexual Reproduction

What is reproduction? Reproduction is the process by which living things produce new individuals of the same type.

Sexual Reproduction in Plants A new individual results from the egg and sperm cells from 2 parents. Offspring may vary from the parents depending on which traits were passed on. Allows for more genetic variation in species.

Asexual Reproduction in Plants Needs only one parent. There is no fusion of egg or sperm and no mixing of genetic material. The offspring are genetically identical to the parent (clones).

What are the types of asexual reproduction? Budding: offspring grow out of the body of the parent (unequal division). Examples: hydra, tapeworm, and cnidarians.

What are the types of asexual reproduction? Binary Fission: the body of the parent divides through the process of mitosis to form 2 individuals. Example: Amoeba, euglena, bacteria

What are the types of asexual reproduction? Fragmentation: the body of the parent breaks into fragments or pieces that grow into new individuals. Examples: flatworms, planarians

What are the types of asexual reproduction? Regeneration: A piece of the parent becomes detached or broken off and a new piece can grow back. Examples: starfish, sea urchins, sand dollars

What are the types of asexual reproduction? Parthenogenesis: females produce eggs, but these develop into young without being fertilized. Examples: some fishes and lizards, several kinds of insects

What are the types of asexual reproduction? Vegetative Reproduction: a new plant is grown from a small piece of the original plant, such as leaves or stems Examples: potatoes, strawberries, spider plants

What are the types of asexual reproduction? Sporulation: reproduction in which spores are produced. Examples: mold, some fungi, and some flowers
