Anther is generally composed of

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Anther**: The anther is a crucial part of the stamen, which is the male reproductive structure in flowering plants. It is typically bulbous in shape and located at the tip of the stamen.

2. **Structure of the Anther**: The anther is described as "bithecus," meaning it has two thecae (or lobes). Each of these thecae is further divided into chambers.

3. **Chambers in the Anther**: The chambers within the thecae are known as microsporangia. These are the sites where pollen grains are formed.

4. **Total Number of Microsporangia**: Since each theca has two chambers, and there are two thecae in the anther, we can calculate the total number of microsporangia:
- 2 thecae × 2 chambers per theca = 4 chambers (or microsporangia).

5. **Conclusion**: Therefore, the anther is generally composed of 4 microsporangia.

**Final Answer**: The anther is generally composed of 4 sporangia.
