Q. Why does Guttation happen?
– Guttation occurs when the soil is very wet at night and water is drained by the roots. It takes up salts, enzymes and other chemicals as water from the soil flows through the guttation process and is called xylem sap. – The cause why guttation occurs at night is because the stomata are dependent on transpiration.
Q. When Guttation occurs which is absent?
Guttation is the loss of water in a dilute solution form which consists salts and minerals and waters when transpiration is low. Guttation is not shown by all the plants and is especially common in humid tropics. It occurs in the absence of light or at night and thus present at the tip of leaves in early morning.
