  • Male trees are planted as ornamentals. Females produce smelly seeds.
• Gnetophyte: Seed-bearing plants that can grow as shrubs, trees, or vines, and share similarities with both gymnosperms and angiosperms.
• Conifer: The most diverse group of gymnosperms, including pines, hemlocks, and spruces.

Pine Trees

• Pollen sacs and ovules are located in cones.
• Fertilization occurs when a pollen grain reaches an ovule.
