Detailed explanation-1: -The correct answer is Stomata. It is a process in which excess water is lost in the form of vapors from the aerial parts of the plant. Mainly through the stomates of leaves.
Detailed explanation-2: -As transpiration occurs, it deepens the meniscus of water in the leaf, creating negative pressure (also called tension or suction). The tension created by transpiration “pulls” water in the plant xylem, drawing the water upward in much the same way that you draw water upward when you suck on a straw.
Detailed explanation-3: -Stomata are small openings in a leaf which help in loss of excess water (transpiration) and also diffusion of gases. Specialised cells known as guard cells surround stomata and their function is to open and close stomatal pore.
