Guttation: Loss of water in the form of liquid from the uninjured margins of the leaves is called guttation.

Guttation

1. Water loss in the form of water drops

2. Occurs through hydathodes*

3. Usually occurs during night

4. Guttation water has many dissolved substances

5. It is an uncontrolled phenomenon

6. It occurs only in some plants like grasses, Colocasia, tomato etc

7. The hydathodes remain open whole day and night
