Fertilization occurs inside

Options

A. Embryo sac
B. Ovule
C. Ovary
D. Carpel.

Answer

To answer the question "Fertilization occurs inside," we need to analyze the options provided: embryo sac, ovules, ovary, and carpel.

**Step 1: Understand the terms.**
- **Carpel**: This is the female reproductive part of a flower and consists of the stigma, style, and ovary. It is a single unit of the gynoecium.
- **Ovary**: This is the basal swollen portion of the carpel that contains ovules. It is where the ovules are housed.
- **Ovules**: These are the structures within the ovary that develop into seeds after fertilization. They are the female gametes.
- **Embryo sac**: This is the structure within the ovule that contains the female gametes (egg cell) and is the site where fertilization occurs.

**Step 2: Identify where fertilization occurs.**
Fertilization is the process where male and female gametes fuse to form a zygote. In flowering plants, this process takes place within the embryo sac, which is located inside the ovule.

**Step 3: Conclusion.**
Based on the definitions and the understanding of the reproductive structures in plants, we can conclude that fertilization occurs inside the **embryo sac**.

**Final Answer: Fertilization occurs inside the embryo sac.**
