Detailed explanation-1: -Guard cells are surrounded by stomatal pores and are located in leaf epidermis.

Detailed explanation-2: -Guard cells are located in the leaf epidermis and pairs of guard cells surround and form stomatal pores, which regulate CO2 influx from the atmosphere into the leaves for photosynthetic carbon fixation.

Detailed explanation-3: -Pair of guard cells are found in stomata where they surround the stomata on the upper and lower epidermis of leaves.

Detailed explanation-4: -Lower epidermis The guard cells regulate the opening and closing of the stomata. Thus they control the exchange of gases between the leaf and the surrounding atmosphere.

Detailed explanation-5: -Stomata are designed to allow gas exchange. Stomata are most frequently found on the bottom (abaxial) side of leaves, but may occur on the top (adaxial) of leaves, stems and even fruit. Subsidiary cells. Guard cells are a pair of kidney-shaped cells that form the opening of the stomate.
