Plants may have both male and female reproductive structures in the same plant (bisexual)  or on different plants (unisexual).

In flowering plants, the unisexual male flower is staminate, i.e., bearing stamens, while the female is pistillate or bearing pistils. In some flowering plants, both male and female flowers may be present on the same individual (monoecious) or on separate individuals (dioecious).

Some examples of monoecious plants are cucurbits and coconuts and of dioecious plants are papaya and date palm. 

Earthworms, sponge, tapeworm and leech, typical examples of bisexual animals that possess both male and female reproductive organs, are hermaphrodites. Cockroach is an example of a unisexual species.
