Detailed explanation-1: -Guttation is the process of water loss from plants in the form of water droplets. This process occurs through the pores called hydathodes, found on the leaf margins. This loss of water takes place in a hot and humid environment.

Detailed explanation-2: -Hydathodes remain open because they are a structural part of a plant found mostly in grasses. There is no such regulation process of its opening or closing as in stomata. Guttation occurs through hydathodes.

Detailed explanation-3: -The presence of too much moisture in the root system causes guttation to take place, as water is squeezed up the stem and to the leaves by root pressure. It is then secreted out of the plant and onto the tips of the leaves or the blades of the plant.

Detailed explanation-4: -Guttation usually occurs in the plants growing in the warm and humid climate. It usually occurs during night or in the morning when the absorption of water exceeds that of the transpiration. Due to which, root pressure is increased in xylem and water comes out through hydathodes.
