Answer

To answer the question "Which is part of the female reproductive system?" we will analyze the options provided and identify the correct one step by step.

### Step-by-Step Solution:

1. **Understanding the Options**: The options given are:
- Embryo sac
- Stamen

2. **Identifying the Female Reproductive Part**:
- **Embryo Sac**: This is known as the female gametophyte in plants. It is located within the ovule and is responsible for the development of the female gametes (eggs).
- **Stamen**: This is the male reproductive organ of flowering plants. It consists of two parts: the filament and the anther, which produces pollen (male gametes).
- **Microspore**: This is a type of spore that develops into male gametophytes (pollen grains) and is part of the male reproductive system.
- **Mother Cell**: This term is vague in this context, but it generally refers to a cell that undergoes division to form spores or gametes. In the context of plants, it usually refers to microspore mother cells, which are part of the male reproductive system.

3. **Conclusion**: Based on the definitions and functions of each option, the **embryo sac** is the only option that is part of the female reproductive system in plants.
