Tetragonal anther consists of

Options

A. One microsporangia
B. Two microsporangia
C. Three microsporangia
D. Four microsporangia

Answer

To solve the question regarding what a tetragonal anther consists of, we can break it down step by step:

### Step-by-Step Solution:

1. **Understanding the Structure of the Anther**:
- The anther is a part of the stamen, which is the male reproductive structure of a flower. It is typically a bag-like structure that sits atop a stalk called the filament.

**Hint**: Remember that the anther is part of the stamen, which plays a crucial role in reproduction in flowering plants.

2. **Identifying the Tetragonal Nature**:
- The term "tetragonal" indicates that the structure has four parts. In botanical terms, "tetra" means four.

**Hint**: Focus on the prefix "tetra" to understand the number of components in the structure.

3. **Microsporangium**:
- The anther contains microsporangia, which are the structures that produce pollen grains. Each microsporangium is essentially a sac that holds the pollen.

**Hint**: Recall that microsporangia are crucial for pollen production, which is essential for plant reproduction.

4. **Counting the Microsporangia**:
- In a tetragonal anther, there are four microsporangia present. This aligns with the definition of "tetragonal".

**Hint**: Visualize the anther's cross-section to see how the four microsporangia are arranged.

5. **Conclusion**:
- Therefore, the tetragonal anther consists of four microsporangia, which contain the pollen grains that will be released during the process of dehiscence.

**Hint**: Remember that the release of pollen is a key event in the reproductive cycle of flowering plants.

### Final Answer:
The tetragonal anther consists of **four microsporangia**.
