Solution
- Transpiration is the process by which plants lose water vapor from their aerial parts, mainly through the stomata in the leaves.
- It mostly occurs during the day when stomata are open for gas exchange.
- This water loss occurs as water vapor into the atmosphere.
- Transpiration helps in the ascent of sap by creating a transpiration pull.
- It also helps in cooling the plant and maintaining water balance.
- Transpiration occurs through three main sites - cuticle, stomata, and lenticels.
