Calculate the total number of meiotic division required to produce 56 pollen grains.

Options

A. 55
B. 14
C. 28
D. 52

Answer

To calculate the total number of meiotic divisions required to produce 56 pollen grains, we can follow these steps:

### Step 1: Understand the process of pollen grain formation
Pollen grains are produced from a spore mother cell through a series of divisions. Each spore mother cell undergoes meiosis, which results in the formation of four haploid cells (pollen grains).

### Step 2: Determine how many pollen grains are produced from one meiotic division
From one meiotic division, 1 spore mother cell produces 4 pollen grains.

### Step 3: Calculate the number of meiotic divisions needed for 56 pollen grains
To find out how many meiotic divisions are needed to produce 56 pollen grains, we divide the total number of pollen grains by the number of pollen grains produced from one meiotic division:

\[ \text{Number of meiotic divisions} = \frac{\text{Total pollen grains}}{\text{Pollen grains per meiotic division}} = \frac{56}{4} \]

### Step 4: Perform the calculation
\[ \frac{56}{4} = 14 \]

### Conclusion
Therefore, a total of 14 meiotic divisions are required to produce 56 pollen grains.
