Guttation is the expelling of excess water or nutrients through tiny openings on leaves and stems. This biological process enables plants to restore balance to their nutrient and water content.

Why is guttation important in plants?

A very important aspect is that plants must balance the amount of water and nutrients they take in. The process by which plants balance the amount of water they take in is called guttation. ... In case there is excess water, the root pressure forces the water out of the tips of the leaves or the blades of the plants.

What is the function of guttation?

The process of guttation occurs when the roots of a plant absorb water from the soil. This creates a pressure inside the plant, and the water is forced out through the hydathodes. As this process occurs, the water picks up chemicals and is no longer simply water; it's called xylem sap.
