The mature male gametophyte in angiosperm is represented by

Options

A. Pollen grain
B. Pistil
C. Embryo sac
D. Anther

Answer

To determine the mature male gametophyte in angiosperms, we can analyze the options provided in the question step by step:

### Step-by-Step Solution:

1. **Understanding Angiosperms**:
- Angiosperms are flowering plants that reproduce through flowers. They have distinct male and female reproductive structures.

2. **Identifying Male Gametophyte**:
- The male gametophyte in angiosperms is responsible for producing male gametes (sperm cells).

3. **Evaluating the Options**:
- **Pollen Grain**: This is the structure that contains the male gametophyte. It is produced in the anther and is responsible for fertilization when it reaches the stigma of a flower.
- **Pistil**: This is the female reproductive part of the flower, which includes the ovary, style, and stigma. It does not represent the male gametophyte.
- **Embryo Sac**: This is the female gametophyte in angiosperms, which contains the ovule and the egg cell. It is not related to the male gametophyte.
- **Anther**: This is the part of the stamen where pollen grains are produced, but it is not the mature male gametophyte itself.

4. **Conclusion**:
- The only option that correctly represents the mature male gametophyte in angiosperms is the **Pollen Grain**.

### Final Answer:
The mature male gametophyte in angiosperms is represented by **Pollen Grain**.
