Answer 2

External fertilization Internal fertilization

It occurs outside the body of the female. It occurs inside the body of the female.

A large number of

gametes are released into the surrounding medium (e.g., water) where fertilization takes place. The male gametes are deposited in the body of the female with the help of copulatory organ.

Organisms that use external fertilization to reproduce must either live in the water or return to the water for reproduction. Animals that have internal fertilization have completely transitioned to life on land.

Examples: Bony fish, Amphibians, most of the Algae etc. Examples: Reptiles, Birds, Mammals, Bryophytes and Tracheophytes (Pteridophytes, Gymnosperms, Angio­sperms), etc.
