The following is/ are true about guttation EXCEPT

• Water is also lost from plants through the guttation.

• Guttation is the loss of water from plants in the form of liquids through hydathodes that are always open on the edge of the leaf.

• Involves stoma.

• The stoma is open to carry out photosynthesis when there is light and closed when dark or when the plant loses too much water on a hot day.
