Male gametophyte of angiosperms/monocots is

Options

A. microsporanguim
B. nucellus
C. microspore
D. stamen

Explanation

To answer the question "Male gametophyte of angiosperms/monocots is," we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Male Gametophyte**:
- The male gametophyte in angiosperms, including monocots, is primarily represented by the pollen grain.

2. **Microspore Formation**:
- Male gametophytes develop from microspores. Microspores are produced through the process of meiosis in a diploid cell known as the microspore mother cell (MMC).

3. **Microspore Characteristics**:
- Microspores are haploid (1N) and uninucleated. This means they contain a single nucleus and half the number of chromosomes compared to the diploid mother cell.

4. **Development into Pollen Grain**:
- After the formation of microspores, they undergo mitotic divisions to develop into pollen grains, which are the immature forms of male gametophytes.

5. **Final Structure**:
- The mature pollen grain contains the male gametes (sperm cells) that will eventually participate in fertilization to form a zygote.

6. **Conclusion**:
- Therefore, the male gametophyte of angiosperms, specifically monocots, is the microspore, which develops into the pollen grain.

### Final Answer:
The male gametophyte of angiosperms/monocots is the **microspore**.
