Which of the following is not true about Angiosperms?

In angiosperms (flowering plants), the dominant and independent phase of the life cycle is the sporophyte, not the gametophyte. The gametophyte stage is highly reduced and dependent on the sporophyte. Angiosperms possess vascular tissue (xylem and phloem), produce two types of spores (heterosporous), and form seeds enclosed within a fruit.
