Which one of the following statements correct

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

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which one of the provided statements is correct regarding plant reproduction and structures involved in it.

2. **Analyzing the Options**:
- **Option 1**: "Tapetum nourishes the developing pollen."
- **Option 2**: "Hard outer layer of pollen is called dentine."
- **Option 3**: "Sporogenous tissue is haploid."
- **Option 4**: "Endothelium produces the microspores."

3. **Evaluating Each Statement**:
- **Option 1**: The tapetum is indeed the innermost layer of the microsporangium wall and surrounds the sporogenous tissue. It is responsible for nourishing the developing pollen grains. This statement is correct.
- **Option 2**: The hard outer layer of pollen is called the exine, not dentine. Dentine is a term used in animal biology, specifically for teeth. Therefore, this statement is incorrect.
- **Option 3**: The sporogenous tissue is diploid (2n), not haploid (n). It consists of cells that will eventually undergo meiosis to produce haploid microspores. Hence, this statement is incorrect.
- **Option 4**: The endothelium does not produce microspores; rather, microspores are produced by the microspore mother cells. The endothelium is a layer in the microsporangium wall that plays a different role. Thus, this statement is also incorrect.

4. **Conclusion**: After evaluating all options, the only correct statement is that "Tapetum nourishes the developing pollen."

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