Question

Gymnosperms differ from most of angiosperms:

• A. In having seeds
• B. In having xylem tracheids
• C. In having naked ovules
• D. None of the above

Answer 1

The correct option is C In having naked ovules

Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary (usually a fruit), while gymnosperms have no flowers or fruits, and have unenclosed or naked seeds on the surface of scales or leaves.
The tracheid is the basic cell in the xylem and all vascular plants have tracheids. Both gymnosperms and angiosperms are vascuclar plants.
