Megasporangium is equivalent to

Options

A. Nucellus
B. Ovule
C. Embryo sac
D. Fruit

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of the Pistil**:
- The pistil is the female reproductive part of a flower, consisting of three main parts: stigma, style, and ovary.

2. **Identifying the Role of the Ovary**:
- The ovary is located at the base of the pistil and contains structures called ovules.

3. **Examining the Ovule**:
- The ovule is a crucial structure within the ovary. It is surrounded by two protective layers known as the outer integument and inner integument.

4. **Identifying the Megasporangium**:
- Inside the ovule, there is a cell known as the megaspore mother cell. This cell undergoes meiosis to produce megaspores.

5. **Formation of the Embryo Sac**:
- The megaspores then divide by mitosis to form the embryo sac, which is essential for fertilization and seed development.

6. **Conclusion**:
- Since the ovule contains the megaspores and is where the development of the megaspores occurs, the ovule is equivalent to the megasporangium.

7. **Final Answer**:
- Therefore, the correct answer to the question "Megasporangium is equivalent to" is **ovule**.
