Which of the following parts of a plant take part in sexual reproduction?

Options

A. Flower
B. Seed
C. Fruit
D. Branch

Explanation

To determine which parts of a plant take part in sexual reproduction, let's analyze the options provided:

1. **Understanding Sexual Reproduction**:
- Sexual reproduction in plants involves the formation of male and female gametes. The fusion of these gametes leads to the formation of a zygote.

2. **Analyzing the Options**:
- **Option A: Flower**:
- The flower is the reproductive part of the plant. It contains both male and female reproductive structures:
- The male part is called the **stamen**, which consists of the **anther** (produces pollen grains containing male gametes) and the **filament**.
- The female part is called the **carpel** (or pistil), which includes the **stigma** (receives pollen), **style** (connects stigma to ovary), and **ovary** (contains ovules with female gametes).
- Thus, the flower plays a crucial role in sexual reproduction.

- **Option B: Seed**:
- The seed contains the developing embryo, which is formed after fertilization. However, the seed itself is not directly involved in the sexual reproduction process; it is the result of it.

- **Option C: Branch**:
- The branch is a part of the plant that supports flowers and fruits but does not participate in the process of sexual reproduction itself.

3. **Conclusion**:
- Among the options provided, the **flower** (Option A) is the part of the plant that takes part in sexual reproduction.

### Final Answer:
The part of the plant that takes part in sexual reproduction is the **flower**.
