What is the primary purpose of guttation in plants?
Understand the Problem
The question is asking about the function or purpose of guttation in plants, which is a physiological process related to water regulation.
Answer
Guttation releases excess water from plants through hydathodes.
The primary purpose of guttation in plants is to allow excess liquid to escape through small openings called hydathodes, preventing the plant from being overwhelmed by too much water.

The primary purpose of guttation in plants is to allow excess liquid to escape through small openings called hydathodes, preventing the plant from being overwhelmed by too much water.
More Information
Guttation often occurs at night when stomata are closed, allowing sap flow to continue via hydathodes. It is different from dew, which forms from condensation of atmospheric moisture.
Tips
A common mistake is confusing guttation with dew, but guttation is the process of water being expelled by the plant, while dew is atmospheric water condensing on the plant.
