Which one of the following statements is correct?

Options

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

Answer

To determine which statement is correct, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Option 1: Hard outer layer of pollen is called entine.**
- This statement is **incorrect**. The hard outer layer of the pollen grain is called **exine**, while **entine** refers to the inner layer of the pollen grain.

2. **Option 2: Sporogenous tissue is deployed.**
- This statement is also **incorrect**. The sporogenous tissue is indeed **diploid** (2n). It consists of a mass of homogeneous cells in the young anther, which differentiate into microspore mother cells that undergo meiosis to form haploid microspores.

3. **Option 3: Endothecium produces the microspores.**
- This statement is **incorrect**. The endothecium is a layer of the anther that develops fibrous thickenings and is involved in the dehiscence of the anther. It does not produce microspores; instead, microspores are produced from the sporogenous tissue.

4. **Option 4: Tapetum nourishes the developing pollen.**
- This statement is **correct**. The tapetum is the innermost layer of the anther and surrounds the sporogenous tissue. It plays a crucial role in nourishing the developing pollen grains, as it has dense cytoplasm and often contains multiple nuclei.

### Conclusion:
The correct statement is: **Tapetum nourishes the developing pollen.**
