Read the following statements regarding gymnosperms: (A) All gymnosperms are homosporous. (B) The multicellular female gametophyte is retained within the megasporangium. (C) The leaves are well-adapted to withstand extremes of temperature, humidity and wind. (D) Ovules are enclosed by an ovary wall before fertilization. How many of the above statements are correct?

Step-by-step solution

Statement (A) is incorrect because all gymnosperms are heterosporous; they produce haploid microspores and megaspores. Statement (B) is correct as the multicellular female gametophyte is retained within the megasporangium (nucellus), which is protected by envelopes. Statement (C) is correct because the leaves in gymnosperms (like conifers) have adaptations such as a needle-like shape, thick cuticle, and sunken stomata to withstand extreme environmental conditions. Statement (D) is incorrect because the ovules in gy
