Question

All gymnosperms are

• A. Heterosporous
• B. Arborescent
• C. Seed plants
• D. All of the above

Answer 1

The correct option is D All of the above

"Gymnosperms" include seed plants other than the angiosperms, or flowering plants. The absence of an enclosing structure is believed to be primitive, thus the first seed plants were gymnosperms.

Gymnosperms are heterosporous i.e., produce two types of spores- microspores (pollen grains) and megaspores.
Arborescent means having the shape or characteristics of a tree. The gymnosperms are also arborescent.

Hence the correct option is D.
