Differentiate between Transpiration and Guttation.

Solution

Transpiration is loss of water vapours from the aerial parts of the plant.
Guttation is loss of water in the form of water droplets from the Hydathodes of plant.
Points of comparison Transpiration Guttation
State The water is lost in the form of water vapour, i.e., in gaseous from. The water is lost in the form of water droplets, i.e., in liquid form
Dissolved solutes The water that is lost does not contain any dissolved solutes. The water that is lost carries dissolved solutes in it.
Duration It occurs during day time. It occurs at night and in the early morning
Reason The evaporation due to increased temperature causes transpiration. The low transpiration and high root pressure causes guttation.
Speed It is a rapid process. It is a slow process.
Location The water is lost through the stomatas, cuticle and lenticels. The water is lost through the hydathodes.
Impact on plant Optimal amount of transpiration is necessary for the movement of water from roots to tips of the plant in xylem vessel. However, high rate of transpiration mat cause wilting of plant. It does not cause wilting of plant.
