Embryo sac represents

Options

A. megaspore
B. female gametophyte
C. megasporophyll
D. megagamete

Answer

To answer the question "Embryo sac represents," we need to analyze the options provided and understand the role of the embryo sac in flowering plants.

### Step-by-Step Solution:

1. **Understanding the Embryo Sac**:
- The embryo sac is a crucial structure in flowering plants (angiosperms) that develops within the ovule.
- It is formed from the megaspore mother cell through a series of divisions.

2. **Identifying the Options**:
- The options given are:
- A) Megaspore
- B) Female gamete
- C) Megasporophyll
- D) Mega gametophyte

3. **Analyzing Each Option**:
- **A) Megaspore**: This is the initial cell that undergoes meiosis to form the embryo sac but is not the same as the embryo sac itself.
- **B) Female gamete**: This refers to the egg cell within the embryo sac, but the embryo sac encompasses more than just the egg cell.
- **C) Megasporophyll**: This is the leaf-like structure that bears the megasporangia and is not synonymous with the embryo sac.
- **D) Mega gametophyte**: This term refers to the entire structure of the embryo sac, which includes the egg cell and other cells.

4. **Conclusion**:
- The embryo sac is best described as a **mega gametophyte**. Therefore, the correct answer is **Option D: Mega gametophyte**.

### Final Answer:
The embryo sac represents the **mega gametophyte**.
