Transpiration happens during the day and is when water is pushed out in the form of vapor, while guttation happens at night and comes in the form of water vapor. This creates a pressure inside the plant, and the water is forced out through the hydathodes. One key aspect of plant life is guttation. This pressure forces the water up and out of the plant.
