PATHOLOGY

Detailed explanation-1: -The turgor pressure in the guard cells controls the opening and closing of the guard cells.

Detailed explanation-2: -A pair of guard cells surrounds each stoma, and these cells control the opening and closing of the stomatal pore between them. Guard cells regulate this opening and closing in response to a wide variety of environmental signals, such as day/night rhythms, CO2 availability, and temperature.

Detailed explanation-3: -Guard cells are large crescent-shaped cells, two of which surround a stoma and are connected to at both ends. These cells enlarge and contract to open and close stomatal pores. Guard cells also contain chloroplasts, the light-capturing organelles in plants.

Detailed explanation-4: -Two guard cells surround each stoma, regulating its opening and closing. Guard cells are the only epidermal cells to contain chloroplasts.

Detailed explanation-5: -cells surrounds each stoma on the leaf surface. Stomata are important because they regulate the uptake of CO2 from the atmosphere for photosynthesis and also the loss of water vapour from the plant during transpiration. The aperture of the stomatal pore is controlled by the two guard cells.
