Answer 2

Mechanism of stomatal transpiration:

The surfaces of spongy mesophyll cells in leaf are exposed to the intercellular spaces.

These cells give out a thin film of water. Water from this film evaporates.

Water vapour formed saturates the air in the intercellular spaces, diffuses into connecting intercellular spaces and reaches the sub-stomatal space. Finally, it escapes in the atmosphere through air.

Water absorbed by roots rises up through the stem and reaches the tissues of leaves.

The cell sap in each cell exerts a turgor pressure outward on the cell wall. This pressure forces some water out of the cell wall into the air space between the cells, i.e. intercellular space.

Here, the water evaporates and the water vapour from intercellular spaces diffuses into the sub-stomatal space from where it finally goes out by diffusion through stomata.
