Endosperm of gymnosperms/Cycas is

Options

A. diploid
B. tetraploid
C. haploid
D. none of these

Answer

**Step-by-Step Solution:**

1. **Understanding Gymnosperms**: Gymnosperms are a group of seed-producing plants that include conifers and cycads. They are characterized by having "naked seeds," which means their seeds are not enclosed within an ovary.

2. **Identifying Cycas**: Cycas is a genus of gymnosperms, and it serves as an example for this question.

3. **Endosperm Formation**: In gymnosperms, the endosperm is formed before fertilization. This is different from angiosperms, where the endosperm develops after fertilization.

4. **Nature of Endosperm**: The endosperm in gymnosperms is derived from the female gametophyte, which is haploid. Since gametes are haploid, the endosperm also has a haploid nature.

5. **Conclusion**: Therefore, the endosperm of gymnosperms, including Cycas, is haploid.

**Final Answer**: The endosperm of gymnosperms/Cycas is haploid.
