Guttation

The exudation of drops of water from the pores of plants, usually at the tips or edges of leaves, due to root pressure in a humid environment.

Transpiration

Root Pressure

The pressure in xylem sap that occurs as a result of the active absorption of mineral ions followed by the osmotic uptake of water into roots from the soil.
