Examples include male and female plants in dioecious species aerial and submerged leaves alternation of gametophyte and sporophyte stages of a life cycle and mesophyll and bundle-sheath chloroplasts.

But unlike most tree species common in the us, the ginkgo is dioecious, meaning trees are male or female.

This paper presents for the first time information on the reproductive ecology of two dioecious fig species, mainly on their phenology, the reproductive behaviors of associated fig wasps and ecology.
