Draw a labelled diagram of a stomatal apparatus with open stomatal pore.

Explanation

### Step-by-Step Text Solution

1. **Understand the Structure of Stomata**: Stomata are tiny openings found on the surface of leaves and stems of plants. They are primarily involved in gas exchange (O2 and CO2) and transpiration.

2. **Identify the Components**: The stomatal apparatus consists of:
- **Guard Cells**: These are specialized cells that surround the stomatal pore. They control the opening and closing of the stomata.
- **Stomatal Pore (Aperture)**: The opening between the guard cells that allows gas exchange.
- **Myelin Sheath**: A protective layer that surrounds the guard cells.
