UPSC CDS-2 – 2018
Transpiration is the loss of water vapor from the plant surface, primarily through stomata.
Secretion is the process where plants release substances produced by their metabolic activity (e.g., nectar, resins, oils).
Excretion is the removal of metabolic waste products, which plants often store internally or deposit in non-living tissues; they don’t have specialized excretory organs like animals.
The specific loss of water in the form of droplets is called guttation.
– It occurs through hydathodes.
– It happens when transpiration is low and root pressure is high.
– Transpiration is the loss of water as vapor.
