GUTTATION: Loss of water from the edges of the leaves through a stomata like opening called hydathode.
TRASPIRATION: Loss of water in the form of vapours from the living through the aerial parts of plant.
SYMPLAST : The water molecules enter into the cell sap & then pass from one cell to another along the concentration gradient.
APOPLAST: The water molecules do not enter into the cell sap. They move through cell wall & inter cellular spaces.
ANTITRANSPIRANTS: A substance applied to the plant for purpose of reducing transpiration is called antitranspirants.
