-What is the main cause of guttation in plants?

Quizplus · Accepted Answer

Guttation is the process by which plants exude droplets of water from the tips of their leaves. This is caused by root pressure - when the soil is saturated and the roots take in more water than they can transpire at the leaves, the excess water is forced out of the leaf tips through specialized structures called hydathodes. Therefore, choice A is the correct answer. Transpiration is the loss of water from the plant's leaves and stems through the stomata, and pressure flow in phloem is the mechanism by which plants transport sugars and other organic compounds from the leaves to other parts of the plant. Plant injury or condensation of atmospheric water do not cause guttation.
