Hint: Transpiration is the transfer and evaporation of water through a plant aerial parts such as leaves, stems, and flowers. The evaporation of water from the surface of the leaves is the most common cause. Water is essential for plants, but only a small portion of the water absorbed by the roots is used for growth and metabolism. The remaining \[97-99.5\% \] is lost by transpiration.

Complete explanation:
Transpiration occurs through stomata. Stomata are usually open during the day and close at night. When the stomata opens, the water near the surface of the leaves turns into vapour and evaporates. Stomata in succulents or CAM plants stay closed throughout the day and open only at night. It also occurs through cuticle and lenticel Since the cuticle, lenticel, and bark lack a closure function, transpiration occurs during the day and night.

Note:
It is stated that transpiration occurs through stomata. Stomata are made up of two guard cells connected by an aperture. It is open during the day and shuts down at night. The turgidity of guard cells is the explanation for this structure's opening and closing.

Additional knowledge:
Water molecules in plant tissues are separated from the aerial parts of the plants during the transpiration process. Only a small portion of the water consumed by plants is used for growth and development. The remainder is expelled by transpiration. Transpiration aids in the transport of water and minerals to various parts of the plant. A water balance is preserved inside the plant due to the constant elimination of water from the plant body. It keeps osmosis going and the cells are rigid.
