Detailed explanation-1: -The stomata are surrounded by a pair of subsidiary cells that are perpendicular to the guard cell.

Detailed explanation-2: -23.2. Guard cells are surrounded by stomatal pores and are located in leaf epidermis.

Detailed explanation-3: -Two guard cells surround each stomatal pore. Here the guard cells are shown in their high turgor state so the pore gapes open.

Detailed explanation-4: -…the epidermis are paired, chloroplast-containing guard cells, and between each pair is formed a small opening, or pore, called a stoma (plural: stomata).

Detailed explanation-5: -Guard cells use osmotic pressure to open and close stomata, allowing plants to regulate the amount of water and solutes within them.
