Ubisch bodies are produced by

Options

A. Middle layer
B. Tapetum cells
C. Pollen mother cells
D. Endothecium.

Answer

**Step-by-Step Solution:**

1. **Understanding Ubisch Bodies**:
- Ubisch bodies are specialized structures found in the anthers of flowering plants. They play a crucial role in the development of pollen grains.

2. **Identifying the Source of Ubisch Bodies**:
- The question asks where Ubisch bodies are produced. We have four options:
- A) Middle layer
- B) Tapetum
- C) Following mother cells
- D) Endocytium

3. **Analyzing the Options**:
- Option A (Middle layer) does not specifically relate to the production of Ubisch bodies.
- Option C (Following mother cells) is not directly involved in the formation of these bodies.
- Option D (Endocytium) is not known for producing Ubisch bodies either.

4. **Focusing on Tapetum**:
- Option B (Tapetum) refers to the tapetal cells, which are known to be secretory or glandular in nature.
- These cells secrete substances such as sporopollenin and compatibility proteins, which are essential for the formation of the outer layer of pollen grains.

5. **Conclusion**:
- Since the tapetum is responsible for the production of Ubisch bodies, the correct answer is **B) Tapetum**.
