Microspores of massulae in Azolla are found in

Options

A. lnducium
B. Sporangium
C. Antheridium
D. Archegonoum

Answer

To answer the question regarding where microspores of massulae in Azolla are found, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Microspores**: Microspores are the male spores that develop into male gametes (pollen grains) in plants. In the context of ferns and other non-flowering plants, they play a crucial role in reproduction.

2. **Identifying the Structure**: In Azolla, which is a type of aquatic fern, the microspores are produced in specific reproductive structures.

3. **Analyzing the Options**:
- **Option 1: Indusium**: This is a thin membranous covering that protects the sporangia in ferns. It does not produce microspores, so this option is incorrect.
- **Option 2: Sporangium**: This is a structure where asexual spores are formed. Microspores are sexual spores, so this option is also incorrect.
- **Option 3: Antheridium**: This is the male reproductive organ in plants where microspores develop into pollen grains. This option is likely correct.
- **Option 4: Archegonium**: This is the female reproductive organ in plants. Since we are discussing microspores (male), this option is incorrect.

4. **Conclusion**: Based on the analysis, the correct answer is that microspores of massulae in Azolla are found in the **Antheridium**.

### Final Answer:
Microspores of massulae in Azolla are found in **Antheridium**.
