Guard cells open or close to increase or decrease the rate of transpiration. They help the plant to adapt to varying environmental conditions such as changes in temperature, light, humidity, or soil moisture.
guard cell and palliside cell
A guard cell is a type of cell found in the epidermis of plant leaves. It is not a tissue or an organ; rather, it is a specialized cell responsible for regulating the opening and closing of stomata to control gas exchange and water loss in plants.
To practice to guard yourself in real life situations
When a potassium ion (K+) enters a guard cell, it creates a solution with a higher osmotic potential inside the cell than outside. This influx of K+ ions increases the osmotic pressure within the guard cell and leads to the uptake of water, causing the guard cell to swell and ultimately leading to stomatal opening.

The scientific name for a guard cell is stoma guard cell. These specialized cells are located in the epidermis of plant leaves and regulate the opening and closing of stomata to control gas exchange and water loss.
Vacuoles in guard cells help regulate the movement of water and ions in and out of the cell, which in turn affects the opening and closing of the stomata. The vacuole can change its volume to control the turgidity of the guard cell, leading to the opening and closing of the stomatal pore for gas exchange.
