Which part of the reproductive structure produces both enzyme & hormone

Options

A. Archesporium
B. Middle layer
C. Tapetum
D. Endothecium

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which part of the reproductive structure produces both enzymes and hormones. The options provided are archaeosporium, metal layer, tapetum, and endothelium.

2. **Identifying the Relevant Structure**: We need to focus on the parts of the reproductive structure that are known for producing enzymes and hormones.

3. **Analyzing the Options**:
- **Archaeosporium**: This is involved in the formation of spores but is not primarily known for enzyme and hormone production.
- **Metal Layer**: This term is not commonly used in the context of plant reproductive structures, making it less likely to be the correct answer.
- **Tapetum**: This is the innermost layer of the anther in flowering plants and is known for its nutritive function.
- **Endothelium**: This layer is involved in the vascular system and does not primarily produce enzymes and hormones.

4. **Focusing on Tapetum**: The tapetum is specifically known for providing nourishment to the developing pollen grains. It produces enzymes, hormones, and proteins necessary for the development of pollen grains.

5. **Conclusion**: Based on the analysis, the correct answer is the **Tapetum**, as it is responsible for producing both enzymes and hormones essential for pollen development.

**Final Answer**: Tapetum
