gymnosperms
Pine tree group
Gymnosperms are plants that produce seeds without enclosing them in fruit—conifers, cycads, ginkgoes, and their relatives.
The name means "naked seed," distinguishing them from angiosperms (flowering plants), whose seeds develop inside protective ovaries.
Gymnosperms dominated ancient forests and include some of the oldest and largest living organisms: bristlecone pines, giant sequoias.
