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.
