A characteristic of tapetum is

Options

A. Multilayered
B. Multinucleate
C. Stores food
D. Nourishes megaspore.

Answer

To determine a characteristic of tapetum, let's analyze the options provided:

1. **Understanding Tapetum**:
- Tapetum is the innermost layer surrounding the microsporangium (the structure where pollen grains are developed).
- Its primary function is to nourish the developing pollen grains.

2. **Evaluating the Options**:
- **Option 1: Multi-layered**: This is incorrect. The tapetum is typically a single layer (unilayered).
- **Option 2: Multinucleate**: This is correct. The tapetum often contains more than one nucleus, which aids in its function of nourishing pollen grains.
- **Option 3: Store food**: This can also be considered correct, as the tapetum may store nutrients that are utilized during the development of pollen grains.
- **Option 4: Nourishes megaspore**: This is incorrect. The tapetum is involved in the nourishment of microspores (male spores), not megaspores (female spores).

3. **Conclusion**:
- While options 2 (multinucleate) and 3 (store food) can be seen as correct, the most specific characteristic of tapetum, based on the question, is that it is multinucleate.

**Final Answer**: The characteristic of tapetum is that it is **multinucleate**.
