Microsporangia of cycas is formed

Options

A. Abaxially on the middle portion of microsporophyll
B. Adaxially on the middle portion of microsporophyll
C. Abaxially on the middle protion of megasporophyll
D. At the extreme tip of microsporophyll

Answer

To solve the question regarding the formation of microsporangia in Cycas, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Microsporangia**: Microsporangia are structures that produce microspores, which eventually develop into male gametophytes (pollen grains) in seed plants.

2. **Identifying the Structure**: In Cycas, which is a genus of cycads, microsporangia are specifically located on microsporophylls. Microsporophylls are the leaf-like structures that bear the microsporangia.

3. **Analyzing the Options**:
- **Option 1**: "Abaxially on the middle portion of microsporophyll" - This option suggests that the microsporangia are located on the underside (abaxial side) of the microsporophyll, which is correct.
- **Option 2**: "Adaxially on the middle portion of the Microsporophyll" - This option suggests that the microsporangia are on the upper side (adaxial side) of the microsporophyll, which is incorrect.
- **Option 3**: "Abaxially on the middle portion of the Megasporophyll" - This option is incorrect because microsporangia are not found on megasporophylls; they are found on microsporophylls.
- **Option 4**: "At the extreme tip of the Microsporophyll" - This option is also incorrect as the microsporangia are not located at the tip.

4. **Conclusion**: Based on the analysis of the options, the correct answer is **Option 1**: "Abaxially on the middle portion of microsporophyll".

### Final Answer:
The microsporangia of Cycas are formed **abaxially on the middle portion of the microsporophyll**.
