exudation
botany
Quick Summary
In botany, exudation refers to the process where substances like resins, saps, or latexes are released from a plant. This occurs through small openings in the plant's tissues. These materials are expelled due to internal hydrostatic pressures and the absorptive forces of plant cells, a passive process that doesn't require energy expenditure from the plant. Excess water can also be eliminated through similar routes via guttation, which is a form of droplet exudation, or transpiration, the evaporation of water.1
