Detailed explanation-1: -Hydathodes are also known as open water pores. These are present at the margins of leaf epidermis. It is the pore at which small xylem vessels of veins of leaves open. When there is positive root pressure of water, the water comes out of these pores by the process called Guttation.

Detailed explanation-2: -Hydathodes are the small pores located on the margins of a leaf. These pores are also called water pores as the water from the leaves moves out through them. The process of water loss from the hydathodes in the form of water droplets is called guttation.

Detailed explanation-3: -Guttation is the process of secretion of water droplets from the pores of some vascular plants like grass. Guttation is often confused with dew droplets that condense from the atmosphere onto the plant’s surface.

Detailed explanation-4: -The loss of water in its liquid phase from the leaves is called guttation.

Detailed explanation-5: -Guttation is the loss of water in solution form through hydathodes. It occurs under the influence of root pressure.
