Correct answer: A. Sequoia is one of the tallest trees
- A. Sequoia is one of the tallest trees
- B. The leaves of gymnosperms are not well adapted to extremes of climate
- C. Gymnosperms are both homosporous and heterosporous
- D. Salvinia, Ginkgo, and Pinus all are gymnosperms
Explanation
(a) : Sequoia sempervirens is the tallest gymnosperm. The leaves of gymnosperms are well adapted to extremes of climate. This is the reason for gymnosperm to flourish in cold areas where instead of rain, snow is the source of water. Gymnosperms are heterosporous i.e., produce two different kinds of sporesmicrospores and megaspores. Salvinia is an aquatic pteridophyte.
