What do flowering and nonflowering plants have in common?

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.
