Guard cells contain chloroplasts for photosynthesis, have a kidney bean shape that allows for stomatal opening and closing, and regulate gas exchange in plants by controlling the size of stomatal pores.
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.

The Cell Wall and the Chloroplast.
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.

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.
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.

When examining an onion cell under a microscope, key features that can be observed include the cell wall, cell membrane, cytoplasm, and nucleus. These features are labeled for identification based on their distinct shapes, sizes, and locations within the cell.

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.
