The process of releasing water through holes in the leaves of plants is called transpiration (option D). Transpiration is the movement of water through a plant and its evaporation from aerial parts, such as leaves, stems, and flowers. It occurs mainly through small openings in the leaves called stomata. As water evaporates from the stomata, it creates a suction force that pulls water up from the roots through the plant's vascular system. This process is essential for the plant's water and nutrient uptake, as well as for maintaining its structure and cooling mechanisms.
