Verified step by step guidance1
Understand that transpiration is the process by which water vapor is lost from plants to the atmosphere.
Recognize that the primary site of transpiration in leaves is through small openings called stomata.
Stomata are tiny pores located on the surface of leaves, primarily on the underside, which facilitate gas exchange.
During transpiration, water vapor exits the leaf through these stomatal openings.
The opening and closing of stomata are regulated by guard cells, which control the rate of transpiration and gas exchange.
