One meiosis produces how many male gametes ?

Options

A. 4
B. 1
C. 2
D. 8

Explanation

To determine how many male gametes are produced from one meiosis, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Starting Cell**:
- The process begins with a microspore mother cell (also known as pollen mother cell), which is diploid (2n).

2. **Meiosis Process**:
- The microspore mother cell undergoes meiosis, which is a reductional division. This results in the formation of four haploid microspores (n).

3. **Formation of Male Gametes**:
- Each haploid microspore then undergoes mitotic division.
- During this division, one microspore divides into two cells: a larger vegetative cell and a smaller generative cell.

4. **Further Division of Generative Cell**:
- The generative cell undergoes another mitotic division, resulting in two male gametes.

5. **Total Male Gametes from One Microspore**:
- Since each microspore produces two male gametes, and there are four microspores produced from one microspore mother cell, the total number of male gametes produced is:
- 4 microspores × 2 male gametes per microspore = 8 male gametes.

### Conclusion:
From one meiosis, a total of **8 male gametes** are produced.
