Caruncle develops from

Options

A. Outer integument
B. Cotyledon
C. Funiculus
D. Inner integument

Answer

**Step-by-Step Solution:**

1. **Understanding Caruncle**:
- A caruncle is a soft outgrowth found at the seed's hilum (the scar where the seed was attached to the ovule). It is formed through the proliferation of cells.

2. **Identifying the Origin**:
- The caruncle specifically develops from the outer integument of the ovule. The outer integument is one of the layers that surround the ovule and contributes to the formation of the seed.

3. **Analyzing the Options**:
- **Outer Integument**: This is the correct answer since the caruncle develops from this part of the ovule.
- **Cotyledon**: This is incorrect. Cotyledons are the first leaves that develop from the seed and do not form the caruncle.
- **Funiculus**: This is also incorrect. The funiculus is the stalk that connects the ovule to the placenta, but it does not develop into the caruncle.
- **Inner Integument**: This option is incorrect as well. The inner integument forms the tegmen, which is the inner covering of the seed, not the caruncle.

4. **Conclusion**:
- Based on the analysis of the options, the caruncle develops from the outer integument.

**Final Answer**: The caruncle develops from the outer integument.
