TRANSIPIRATION

Transpiration is the process by which plants lose water through the stomata in the leaves.

Water flows from the roots to the leaves through the xylem vessels. It enters the spongy mesophyll by osmosis. The spongy mesophyll has substomatal air spaces where water enters as water vapor. As a result, the concentration of water vapor in the substomatal air spaces becomes higher than the concentration of water vapor in the air. This causes water to diffuse into the atmosphere through the stomata.
