Answer Details
Oozing out of water from the leaves of plants in a humid environment is known as guttation. Guttation occurs when the roots of a plant absorb more water than the plant can transpire through its leaves. The excess water pressure forces water out of special pores called hydathodes, located on the tips or edges of leaves. The water that is exuded through these pores can contain sugars, amino acids, and minerals dissolved in it. Guttation usually occurs in plants during the night or early morning when the humidity is high and the soil is moist.
