What two classes of vertebrate use external fertilization?
Two classes:Fish and Reptileswhat is interior and exterior fertilization?Internal fertilization is when the sperm is directly deposited into the female, who produces eggs and fertilizes them in her body. External fertilization is when the sperm and eggs are released outside of the body and meet outside of the body, not like how chithra described. Birds do not have external fertilization, the fertilization still occurs in the body, they just do not produce live young.Examples of external fertilization are in plants like moss or algae, where the sperm and eggs meet outside of the parent's body and produce a zygote, which then grows into a mature plant. External fertilization in animals are usually in marine organisms, like sponges, because the sperm needs to swim in water to meet the egg.-Your Welcome
