Correct Answer
(C) Sequoia is one of the tallest trees
Solution & Explanation
Answer: (C) Sequoia is one of the tallest trees. Solution: The giant redwood tree Sequoia is a gymnosperm and is among the tallest tree species, so statement (3) is correct. Statement (1) is wrong because gymnosperms are heterosporous only (not both homosporous and heterosporous); statement (2) is wrong because Salvinia is a pteridophyte, not a gymnosperm; statement (4) is wrong because gymnosperm leaves ARE well-adapted to withstand extremes of climate (needle-like leaves, thick cuticle, sunken stomata). NCERT Reference: Class XI Biology, Plant Kingdom, p.32, lines 32-33 — "the giant redwood tree Sequoia is one of the tallest tree species".
