Detailed explanation-1: -Carbon dioxide and oxygen cannot pass through the cuticle, but move in and out of leaves through openings called stomata (stoma = “hole"). Guard cells control the opening and closing of stomata.
Detailed explanation-2: -Stomata (noun, “STO-mah-tah”, singular “stoma”) These are the small pores in plant stems or leaves that allow carbon dioxide in and oxygen and water vapor out. Each tiny hole is surrounded by a pair of cells called guard cells.
Detailed explanation-3: -Stomata resemble doughnuts-a circular pore with a hole in the middle for gas to enter or leave the plant. The pore consists of two cells-each known as a guard cell.
Detailed explanation-4: -Transpiration occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves.
