Megaspore develops into multicellular structure called -

Options

A. Male gametophyte
B. Female gamete
C. Female gametophyte
D. Megaspore mother cell

Answer

To answer the question "Megaspore develops into multicellular structure called -", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Megaspores**:
- Megaspores are produced in heterosporous plants, which include gymnosperms and angiosperms.

2. **Formation of Megaspores**:
- The process begins with the megaspore mother cell, which undergoes meiosis to produce megaspores.

3. **Development of Megaspores**:
- Out of the megaspores produced, typically one megaspore survives and develops further.

4. **Multicellular Structure**:
- The surviving megaspore develops into a multicellular structure known as the female gametophyte.

5. **Function of Female Gametophyte**:
- The female gametophyte contains archegonia, which are the female reproductive organs. In angiosperms, this structure is specifically referred to as the embryo sac.

6. **Conclusion**:
- Therefore, the correct answer to the question is that the megaspore develops into a multicellular structure called the female gametophyte.

### Final Answer:
Megaspore develops into multicellular structure called **female gametophyte**.
