A typical angiospermic anther is bilkobed and tet ragonal consisting of

Options

A. Two microsporangia
B. Three microsporangia
C. Four microsproangia
D. Only one microsporangia

Answer

To solve the question regarding the structure of a typical angiospermic anther, we will break down the information step by step.

### Step-by-Step Solution:

1. **Understanding the Structure of the Anther**:
- A typical angiospermic anther is described as bilobed and tetragonal. This means it has two lobes (bilobed) and a four-sided shape (tetragonal).

2. **Components of the Anther**:
- Each lobe of the anther contains structures called thecae. In a bilobed anther, there are two lobes, and each lobe contains two thecae.

3. **Microsporangia in the Anther**:
- The microsporangia are the structures that produce pollen grains. In each theca, there is one microsporangium. Since there are two thecae in each lobe and two lobes, we can calculate the total number of microsporangia.

4. **Calculating the Total Microsporangia**:
- Each lobe has 2 thecae, and with 2 lobes, the total number of microsporangia is:
- 2 thecae/lobe × 2 lobes = 4 microsporangia.

5. **Conclusion**:
- Therefore, a typical angiospermic anther consists of **4 microsporangia**.

### Final Answer:
A typical angiospermic anther is bilobed and tetragonal consisting of **4 microsporangia**.
