If there are 1280 microspores in a tetralocular anther. How many microspore mother cells will be there in its each pollen chamber

Options

A. 80
B. 160
C. 240
D. 1280

Answer

To solve the problem of how many microspore mother cells are present in each pollen chamber of a tetralocular anther containing 1280 microspores, follow these steps:

### Step-by-Step Solution:

1. **Understand the relationship between microspore mother cells and microspores**:
- Each microspore mother cell undergoes meiosis to produce 4 microspores.

2. **Calculate the total number of microspore mother cells needed for 1280 microspores**:
- Since 1 microspore mother cell produces 4 microspores, to find the total number of microspore mother cells required for 1280 microspores, we divide the total number of microspores by 4:
\[ \text{Total microspore mother cells} = \frac{1280 \text{ microspores}}{4 \text{ microspores/mother cell}} = 320 \text{ microspore mother cells} \]

3. **Determine the number of pollen chambers**:
- A tetralocular anther has 4 pollen chambers.

4. **Calculate the number of microspore mother cells in each pollen chamber**:
- To find the number of microspore mother cells in each chamber, divide the total number of microspore mother cells by the number of chambers:
\[ \text{Microspore mother cells per chamber} = \frac{320 \text{ microspore mother cells}}{4 \text{ chambers}} = 80 \text{ microspore mother cells} \]

### Final Answer:
The number of microspore mother cells in each pollen chamber is **80**.
