Detailed explanation-1: -Guttation is not shown by all plants.

Detailed explanation-2: -Guttation is an exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses. It happens certain plants that have vascular systems, such grass, wheat, barely, tomatoes, strawberries and other small plants.

Detailed explanation-3: -Guttation happens in certain plants that have vascular systems, such as grass, wheat, barley, tomatoes, strawberries, and other small plants. Since guttation relies on pressure, it can’t occur in large plants, such as trees, because the pressure required to force the water out is too large.

Detailed explanation-4: -Guttation is the loss of water in a dilute solution form which consists salts and minerals and waters when transpiration is low. Guttation is not shown by all the plants and is especially common in humid tropics. It occurs in the absence of light or at night and thus present at the tip of leaves in early morning.
