Guttation vs Transpiration
Guttation: It is the removal of excess of water in the form of water droplets is called guttation. This can be seen only in shurbs and herbs. And not in higher plants. Water droplets are found when the evaporation is low, during early morning and evening, droplets can be seen on the tip of veins and surface of leaves. Guttation is found only in Root pressure type of transportation of plants. Transpiration: It is the process of removal of water from the upper surface of leaves through stomatal opening in the form of water vapour is called Transporation. This is seen in higher plants and takes place when the excess of water is present. It creates tranpiration pull for absorption and transport of plants. It supplies water for photosynthesis. Also transports minerals to the various parts of the plant. It keeps the cell turgid and cools leaves surface by evaporative cooling.
