Difference Between Transpiration And Guttation

Transpiration is defined as the process of water loss in the form of vapor from the aerial parts of plants. It is not a type of secretion and occurs in high temperatures through all the parts of the leaf. It is favored by dry conditions and can be influenced by many factors such as environment humidity, wind flow, nature of stomata, etc. Guttation is a type of secretion which occurs in low-temperature conditions only through the margin of the leaves. Both these process cause permanent loss of water from the plants. Below are major differences between transpiration and guttation for better understanding.
