Gymnosperm seeds are naked due to lack of

Options

A. Pericarp
B. Perianth
C. Nucellus
D. Integuments.

Answer

**Step-by-Step Solution:**

1. **Understanding Gymnosperms**: Gymnosperms are a group of seed-producing plants that include conifers. The term "gymnosperm" means "naked seeds," which indicates that their seeds are not enclosed in an ovary.

2. **Identifying Seed Characteristics**: In gymnosperms, the seeds are exposed and not surrounded by a fruit. This is a key characteristic that differentiates them from angiosperms, where seeds are enclosed within a fruit.

3. **Analyzing the Options**:
- **Pericarp**: This is the part of a fruit that develops from the ovary wall after fertilization. Since gymnosperms do not form fruits, they lack a pericarp.
- **Perianth**: This refers to the outer parts of a flower, including the calyx and corolla. This is not related to seed formation.
- **Nucellus**: This is the central part of an ovule where the embryo develops. It is not responsible for the naked nature of the seeds.
- **Integuments**: These are the outer layers of the ovule that develop into the seed coat after fertilization. While they are part of the ovule, they do not contribute to the naked condition of the seeds.

4. **Conclusion**: The correct answer is **pericarp** because gymnosperms do not have an ovary, and therefore, there is no fruit wall (pericarp) to enclose the seeds. This lack of pericarp is what makes the seeds "naked."

**Final Answer**: Gymnosperm seeds are naked due to lack of **pericarp**.
