Gymnosperm Cone

Gymnosperm Cone


A gymnosperm is a vascular plant that produces seeds lacking an outer fruit. Normally these seeds are contained in cones. Gymnosperms have male and female cones. The male cones produce sperm, which are contained in pollen grains. Male cones are normally smaller than female cones.  The female cones produce eggs, which are contained in ovules. Female cones have a sticky resin that “catches” the pollen released by the male cone. When fertilized, the female cone enlarges and the scales separate. This separation allows the seeds to drop out of the cone and are dispersed by animals, such as chipmunks & squirrels.
