Detailed explanation-1: -The pore consists of two cells-each known as a guard cell. They can swell or shrink to open or close the pore, which is critical for regulating gas exchange for photosynthesis, as well as moisture levels in tissues.

Detailed explanation-2: -A stoma is a pore, found in the leaf and stem epidermis that is used for gas exchange. The pore is bordered by a pair of specialised parenchyma cells known as guard cells which are responsible for regulating the size of the opening. The inner wall of the guard cells is thicker than the outer wall.

Detailed explanation-3: -Plant leaves have openings (pores) known as a stomata where gasses can enter/exit the plant. Explain reasons why stomata are found on the bottom of leaves. It might be helpful to think of the comparable structure (nose) in humans and how its openings are oriented.

Detailed explanation-4: -Stomata, formed by a pair of kidney-shaped guard cells, are tiny pores in leaves. They act like mouths that plants use to “eat” and “breathe.” When they open, carbon dioxide (CO2) enters the plant for photosynthesis and oxygen (O2) is released into the atmosphere.
