the main cause of guttation in plants is root pressure.during night wen root pressure is high sometimes den due to this pressure watery drops ooze out with the assistance of special structures which help in guttation called the hydathodes
because the catabolic process is low. in plants catabolic product are used in anabolic process. and excess amount of water s excerated by tranpiration(in day time) and by guttation (in night time)
in plants
Because overnight when the air gets colder, it can not hold as much moisture, so liquid water condensates on any surface it can, including plants. On plants this is known as guttation water and is normally found at the tips or lowest points on the leaves
Glycolysis
Guttation is the process by which plants release excess water in the form of droplets through specialized structures called hydathodes. This usually happens at night when transpiration is low and root pressure is high. Guttation droplets can sometimes be mistaken for dew.
Plants get rid of water and minerals mainly through Transpiration. Some plants also release them through Guttation. But, Guttation is seen very rarely in only a few plants like Anthurium and Grass.

An aquatic plant with submerged leaves
The process is called transpiration, whereby water vapor is released through the stomata of plant leaves. A different process that releases liquid water from the xylem is called guttation.
Guttation is caused by root pressure causing more water to enter the leaves than is transpired. Where dew is condensed moisture produced during transpiration. Determining by observation: 1) Many plants do not under go Guttation (Due to low root pressure), so guttation is mostly isolated to grass, and small herbaceous eudicots. 2) Transpiration is low at night, which would support Guttation of plants over dew during these times. During the day even the plants that can undergo guttation can't keep up with transpiration, so during these times droplets are probably dew. Experiment wise: 3) If you were setting up an experiment you could try to label the ground water/ions, if the labeled is showing up on the leaf surface you have guttation.
Transpiration; it occurs through the stomata of the plants.
The structure in the epidermis that gaseous exchange occurs in plants is through the stomata. A stomata is a tiny opening or pore in the epidermis.
