Name the following:
The pores through which leaves exchange gases.

Answer

**Step-by-Step Solution:**

1. **Identify the Function of the Pores**: The question asks for the name of the pores in leaves that are responsible for gas exchange. These pores play a crucial role in the process of photosynthesis and respiration in plants.

2. **Name the Pores**: The pores through which leaves exchange gases are called "stomata".

3. **Understand the Role of Stomata**: Stomata facilitate the exchange of gases; they allow carbon dioxide (CO2) to enter the leaf for photosynthesis and oxygen (O2) to exit as a byproduct.

4. **Identify Surrounding Cells**: Stomata are surrounded by specialized cells known as "guard cells". These cells regulate the opening and closing of the stomata based on the plant's needs.

5. **Explain the Process of Gas Exchange**: During the day, stomata generally open to allow gas exchange, and they close at night to conserve water. The turgidity of the guard cells determines whether the stomata are open or closed.

**Final Answer**: The pores through which leaves exchange gases are called **stomata**.
