passage of water through the stomata of the leaves.

|
loss of water vapour from the leaves and the stem.

Detailed explanation-1: -Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is ‘pulled’ into the leaves.
Detailed explanation-2: -Transpiration occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves.
Detailed explanation-3: -The loss of water from the leaves of plants as water vapour through the stomata is called as transpiration.
Detailed explanation-4: -Transpiration is defined as the physiological loss of water in the form of water vapor. It also evaporates from the surfaces of leaves, flowers, and stems. Transpiration has two main functions namely, cooling the plant and pumping water and minerals to the leaves for photosynthesis.
Detailed explanation-5: -Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism.
