Difference Between Transpiration And Guttation

Transpiration and guttation are the two important process of removal of excess water from the plants. However, the two processes are different from each other. Transpiration is the removal of water from the stomata present on the leaves. On the contrary, guttation is the process of removal of water from the hydathodes.

Below are major differences between transpiration and guttation for better understanding.

Transpiration vs Guttation

Following are the important difference between transpiration and guttation:

Transpiration Guttation
Transpiration occurs through the stomata and lenticels. Guttation takes place through hydathodes.
Loss of Water as water vapour. Loss of water as liquid water.
It occurs during the day. It occurs during early morning or at night.
Takes place at high temperature  Takes place at low temperatures.
Dry conditions favor it Resisted by dry conditions.
Excessive transpiration results in wilting. Guttation never results in wilting.
Water lost in transpiration through simple diffusion. Water lost in guttation is not diffusion.
Can be checked by the opening and closing of stomata. Cannot be regulated as hydathodes do not open or close.
The rate of transpiration is reduced during humid days. Humidity enhances the rate of guttation.
Root pressure is not involved in this process. Root pressure plays a vital role in this process.
Only pure water is evaporated. Eliminates sugars, salts and amino acids.
Occurs in terrestrial and herbaceous plants. Occurs only in herbaceous plants.

Transpiration

Transpiration is defined as the process of water loss in the form of vapour 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 favoured by dry conditions and can be influenced by many factors such as environment humidity, wind flow, nature of stomata, etc.

Guttation

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.

Frequently Asked Questions

What is transpiration?

Transpiration is the removal of excess water from the leaves of the plants in the form of water vapour. The water is removed through minute pores called stomata.

What is the function of hydathodes?

Hydathodes are special structures that discharge water from the interior of the leaf to the surface. This process is known as guttation.
