Flowering plants or Angiosperms have seeds that are enclosed within an ovary (usually a fruit), while Gymnosperms have no flowers or fruits, and have “naked” seeds.
Both classes:
· Have differentiation of the sporophyte (root, stem, and leaves),
· Produce pollen for fertilization,
· Seeds bearing plants (belong to the class known as Spermatophyta),
· The vascular system,
· Reduced gametophytic phase.
