Eg : Animals -Jelly fish, Earthworm, slugs etc. Plants : castor bean , cucumber, papaya etc. Organisms with male and female sex organs in different individuals are called as unisexual a or dioecious. Eg : Animals  : mammals, birds, insects etc. Plants  : aspargus, holly plant, ginkgo tree etc. Sexual reproduction is better than asexual reproduction in the fact that it causes variation which is important for evolution.
