Which of the following option about tapetum is correct?

Options

A. nutritive tissue
B. sporogenous tissue
C. protective and haploid tissue
D. external layer of mcirosporangium wall

Answer

**Step-by-Step Solution:**

1. **Understanding Tapetum**: The tapetum is the innermost layer of the microsporangium in flowering plants. It plays a crucial role in the development of pollen grains.

2. **Identifying Functions of Tapetum**: The primary function of the tapetum is to provide nutrition to the developing pollen grains. This makes it a nutritive tissue.

3. **Analyzing the Options**:
- **Option 1: Nutritive tissue** - This is correct as the tapetum provides nourishment to the pollen grains.
- **Option 2: Sporogenous tissue** - This is incorrect because the tapetum is not involved in the formation of spores; it supports the developing spores.
- **Option 3: Protective and haploid tissue** - This is also incorrect. The protective function is carried out by the outer layers (epidermis, endothelium, and middle layers), and the tapetum is diploid, not haploid.
- **Option 4: External layer of microsporogenesis wall** - This is incorrect as the tapetum is not the external layer; it is the innermost layer.

4. **Conclusion**: Based on the analysis, the correct statement about tapetum is that it is a nutritive tissue.

**Final Answer**: The correct option about tapetum is that it is a nutritive tissue.
