Quizplus · Accepted Answer

Guttation is the process by which water is lost in liquid form at the edges of the leaves of herbaceous plants. This is different from transpiration, where water is lost in vapor form through the stomata on the leaves. Guttation occurs when there is excess water in the plant and the stomata are closed, so the water is forced out through specialized structures at the edges of the leaves. Cohesion, phloem loading, mesophyll adhesion, and aeration are not related to the loss of water at the edges of leaves through guttation.
