Multiple Choice

Which statement correctly describes the vasculature found in angiosperms and gymnosperms?

• A) Angiosperms contain secondary xylem, whereas gymnosperms rely on primary xylem alone for structural support and water conduction.
• B) The presence of phloem companion cells in angiosperms indicates that they evolved before gymnosperms-a group that subsequently lost this feature.
• C) Vessel elements in the xylem of angiosperms have allowed members of this group to surpass gymnosperms in terms of both life span and height.
• D) Both angiosperm and gymnosperm vascular cells contain fiber to support secondary growth-a trait that distinguishes them from their seed fern ancestors.
• E) With the exception of the gnetophytes, living gymnosperms have only tracheids for conducting water and providing structural support, whereas angiosperms typically contain vessel elements and fibers.
