* Guard cells: These are specialized cells that surround the stoma, controlling its opening and closing.
* Stoma: This is the actual opening or pore between the guard cells.
Stomata are crucial for gas exchange in plants, allowing for the uptake of carbon dioxide (CO2) for photosynthesis and the release of oxygen (O2) as a byproduct. They also play a role in regulating water loss through transpiration.
