Which one of the following statements is correc

Options

A. Tapetum nourishes the developing pollen
B. Hard outer layer of pollen is called intine
C. Sporogenous tissue is haploid
D. Endothecium produces the microspores

Answer

To determine which statement is correct among the options provided, we will analyze each statement one by one based on our understanding of the structure and function of the anther in flowering plants.

### Step-by-Step Solution:

1. **Understanding the Tapetum**:
- The tapetum is the innermost layer of the anther wall. Its primary function is to nourish the developing pollen grains (microspores).
- **Statement Analysis**: "Tapetum nourishes the developing embryo."
- This statement is incorrect because the tapetum nourishes the developing pollen grains, not the embryo.

2. **Identifying the Hard Outer Layer of Pollen**:
- The outer layer of pollen grains is known as the exine, while the inner layer is called the intine.
- **Statement Analysis**: "Hard outer layer of pollen is called entine."
- This statement is incorrect because the hard outer layer is called exine, not entine.

3. **Examining the Sporogenous Tissue**:
- Sporogenous tissue is the tissue that gives rise to microspores through meiotic division. This tissue is diploid (2n) before meiosis.
- **Statement Analysis**: "Sporogenous tissue is haploid."
- This statement is incorrect because sporogenous tissue is diploid before meiosis.

4. **Function of Androthecium**:
- The androecium is the male reproductive part of the flower, which consists of stamens. The anther, part of the stamen, produces microspores.
- **Statement Analysis**: "Androthecium produces the microspore."
- This statement is partially correct; however, it is more accurate to say that the anther (part of the androecium) produces microspores.

5. **Conclusion**:
- After analyzing all four statements, the first statement is the only one that is correct: "Tapetum nourishes the developing pollen grain."

### Final Answer:
The correct statement is: **"Tapetum nourishes the developing pollen grain."**
