The microsporophylls of Pinus has

Options

A. Many microsporangia
B. No microsporangia
C. 2 microsporangia
D. Only one microsporangium

Explanation

To answer the question "The microsporophylls of Pinus has," we will break down the information step by step.

### Step-by-Step Solution:

1. **Understanding Microsporophylls**: Microsporophylls are the leaf-like structures that bear microsporangia (pollen sacs) in seed plants. In the case of Pinus, which is a genus of coniferous trees, these structures are crucial for reproduction.

2. **Identifying Microsporangia**: In Pinus, each microsporophyll typically contains microsporangia, which are responsible for producing pollen grains.

3. **Counting Microsporangia**: According to the information provided, each microsporophyll of Pinus has two microsporangia. This is a characteristic feature of the reproductive structure in Pinus.

4. **Understanding Pollen Development**: The microsporangia undergo meiosis to produce microspores, which then develop into pollen grains. In the case of Pinus, the pollen grains are formed in a four-celled stage, consisting of two prothallial cells, one generative cell, and one tube cell.

5. **Conclusion**: Based on the above points, the correct answer to the question is that the microsporophylls of Pinus have **two microsporangia**.

### Final Answer:
The microsporophylls of Pinus has **two microsporangia**.
