In gymnosperms, the ovule is naked because :-

Options

A. ovary wall is absent
B. integuments are absent
C. perianth is absent
D. nucellus is absent

Answer

**Step-by-Step Solution:**

1. **Understanding Gymnosperms**: Gymnosperms are a group of seed-producing plants that include conifers, cycads, and ginkgo. They are characterized by having seeds that are not enclosed in an ovary.

2. **Defining Key Terms**:
- **Ovule**: The structure in seed plants that develops into a seed after fertilization.
- **Ovary Wall**: The tissue that surrounds and protects the ovule in flowering plants (angiosperms).
- **Integuments**: Layers of tissue that surround the ovule and develop into the seed coat.
- **Perianth**: The outer part of a flower, which includes the petals and sepals.
- **Nucellus**: The central part of the ovule, which contains the female gametophyte.

3. **Identifying the Key Feature**: In gymnosperms, the ovule is described as "naked" because it is not enclosed by an ovary wall. This is a distinguishing feature of gymnosperms compared to angiosperms, where the ovule is enclosed within an ovary.

4. **Analyzing the Options**:
- **Ovary wall is absent**: This is true for gymnosperms, as their ovules are not enclosed.
- **Integuments are absent**: This is incorrect; gymnosperms do have integuments.
- **Perianth is absent**: This is not relevant to the naked ovule concept.
- **Nucellus is absent**: This is also incorrect; the nucellus is present in gymnosperms.

5. **Conclusion**: The correct answer is that the ovule is naked because the ovary wall is absent in gymnosperms.

**Final Answer**: In gymnosperms, the ovule is naked because the ovary wall is absent.
