In leaves transpiration takes place through _________.

Stomata

The correct answer is Option (1) – Stomata

Transpiration, the process of water loss from plant tissues, primarily occurs through tiny pores called stomata, which are present on the surface of leaves. Stomata are surrounded by specialized cells called guard cells, which can open and close to regulate the exchange of gases and water vapor between the plant and the surrounding atmosphere. When the guard cells swell, they create an opening, allowing water vapor to diffuse out of the leaf. This process helps plants to regulate water balance, temperature, and gas exchange necessary for photosynthesis and respiration. While water loss can also occur through other surfaces of the plant, such as the cuticle and lenticels, stomata are the primary sites for transpiration in leaves.
