How many microsporangia are present in an angiospermic anther?

Options

A. 2
B. 3
C. 4
D. 5

Answer

To determine how many microsporangia are present in an angiospermic anther, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of an Anther**:
- An angiospermic anther is typically bilobed, meaning it has two lobes.

2. **Identifying the Microsporangia**:
- Each lobe of the anther contains two microsporangia (also known as pollen sacs).

3. **Calculating the Total Number of Microsporangia**:
- Since there are two lobes and each lobe has two microsporangia, we can calculate the total number of microsporangia as follows:
- Number of lobes = 2
- Microsporangia per lobe = 2
- Total microsporangia = Number of lobes × Microsporangia per lobe = 2 × 2 = 4

4. **Conclusion**:
- Therefore, the total number of microsporangia present in an angiospermic anther is **4**.

### Final Answer:
The correct answer is **4 microsporangia**.
