Explain the mechanism of functioning of stomata?

Explanation

### Step-by-Step Solution:

1. **Definition of Stomata**: Stomata are small openings located primarily on the leaves and stems of plants. They play a crucial role in gas exchange and transpiration.

2. **Structure of Stomata**: Each stoma consists of a central opening known as the stomatal pore, which is flanked by two specialized cells called guard cells. These guard cells regulate the size of the stomatal opening.

3. **Function of Stomata**: The main functions of stomata include:
- Facilitating the exchange of gases, such as carbon dioxide (CO2) and oxygen (O2), which are essential for photosynthesis and respiration.
