Detailed explanation-1: -Water vapour comes out from the plant leaf through the stomatal opening. Through the same stomatal opening, carbon dioxide diffuses into the plant during photosynthesis.

Detailed explanation-2: -In the air spaces, the water changes state and turns from a liquid into a gas called water vapor. Because there is a higher concentration of water vapor inside the leaf than outside, the water vapor moves out of the leaf through the stomata by diffusion. This process is known as evaporation.

Detailed explanation-3: -When plants have more water in their leaves than they need, they get rid of this extra water through a process called transpiration. During transpiration, water evaporates from tiny holes in the surfaces of leaves into the air. These tiny holes are called stomata.

Detailed explanation-4: -Most of the water a plant loses is lost due to a natural process called transpiration. Plants have little pores (holes or openings) on the underside of their leaves, called stomata. Plants will absorb water through their roots and release water as vapor into the air through these stomata.

Detailed explanation-5: -Water enters and leaves cells through osmosis, the passive diffusion of water across a membrane. In plants, water always moves from an area of higher water potential to an area of lower water potential.
