Select the correct statement.
- 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.
Answer & Solution
Correct Answer
(A) Sequoia is one of the tallest trees.
Step-by-step Solution
Detailed 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.
