In an mature pollen how many nucleus are present name them

Answer

**Step-by-Step Solution:**

1. **Understanding Pollen Grain Formation**:
- Pollen grains are formed from pollen mother cells (PMCs) located in the microsporangia (also known as pollen sacs).

2. **Identifying the Structure of Pollen Grains**:
- A mature pollen grain is considered a male gametophyte, which means it is involved in the male reproductive process.

3. **Components of a Pollen Grain**:
- A mature pollen grain consists of two types of cells:
- **Vegetative Cell**: This cell is larger and is responsible for the growth of the pollen tube.
- **Generative Cell**: This cell is smaller and divides to form two male gametes (sperm cells).

4. **Counting the Nuclei**:
- In total, a mature pollen grain contains **two nuclei**:
- One nucleus from the vegetative cell.
- One nucleus from the generative cell.

5. **Final Answer**:
- Therefore, in a mature pollen grain, there are **two nuclei**: one from the vegetative cell and one from the generative cell.
