Anther of angiosperm generally composed of

Options

A. One sporangium
B. Two sporangia
C. Three sporangia
D. Four sporangia

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Anther**: The anther is a key component of the stamen, which is the male reproductive part of flowering plants (angiosperms). The stamen consists of two parts: the filament and the anther.

2. **Identifying the Anther's Shape**: The anther is typically described as a bilobed structure, meaning it has two lobes. Each lobe contains specific structures that are crucial for reproduction.

3. **Counting the Thecae**: Each lobe of the anther contains two thecae. Therefore, with two lobes, the total number of thecae in the anther is four (2 thecae per lobe × 2 lobes = 4 thecae).

4. **Understanding Microsporangia**: Each theca contains a microsporangium, which is responsible for producing pollen grains. Since there are four thecae in total, there are also four microsporangia in the anther.

5. **Conclusion**: Thus, the anther of angiosperms is generally composed of four microsporangia.

**Final Answer**: The anther of angiosperm generally consists of 4 microsporangia.
