An anther has 1200 pollen grains. How many pollen mother cells must have been there to produce them ?

Explanation

To determine how many pollen mother cells are needed to produce 1200 pollen grains, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Role of Pollen Mother Cells**: Pollen mother cells (also known as microsporocytes) undergo meiosis to produce pollen grains. Each pollen mother cell divides meiotically to form four haploid pollen grains.

2. **Calculate the Number of Pollen Grains Produced by One Pollen Mother Cell**: Since one pollen mother cell produces 4 pollen grains, we can use this information to find out how many pollen mother cells are needed for a total of 1200 pollen grains.
