Gymnosperms are seeded plants whose seeds are naked, and are not enclosed in fruits. The male and female gametophyte structures develops in male and female cones. Male and female cones borne on separate plants. In gymnosperms pollen grains are carried by winds to the naked ovules. Thus, pollination in gymnosperm is anemophily. After deposition of pollen grains on the ovule, pollen grain germinates, forming pollen tube which carries sperm cell preparation to fertilize with egg.
