State the sructure of transpiration and guttation and both where the occur

Transpiration is loss of water from the surface of leaves in the form of water vapour while guttation is exudation of water from the surface of leaves in the form of drops. Transpiration takes place through stomata while guttation takes place through hydathodes.

Guttation usually occurs at the margins and the tips of the leaves. Transpiration occurs throughout the general surface of the leaves and the young stems.
