What does transpiration mean?

: the process by which plants give off water vapor through openings in their leaves. transpiration. noun.

What is transpiration in animals?

(animal physiology) The process of giving off water vapour through the skin or mucous membranes; also sometimes referred to as sweating, which is the evaporation of water together with a small amount of sodium chloride via the sweat glands of the skin.

What is transpiration of a plant?

Transpiration: The release of water from plant leaves Plants put down roots into the soil to draw water and nutrients up into the stems and leaves. Some of this water is returned to the air by transpiration.

What is transpiration for class 6th?

Transpiration is the process of losing water from the surface of the leaf through stomata. Transpiration helps a plant in cooling the leaves and transporting the nutrients.

What is the definition of transpiration in plants?

Definition of Transpiration in Plants. Transpiration in plants can define as the natural process, where a plant releases excessive water into the atmosphere in the form of water vapour like a human body does. A human releases its excessive water by the process refers as “Sweating” whereas, in plants, it commonly refers to as “Transpiration”.

Where does the majority of transpiration take place?

A majority (90%) of transpiration takes place via leaf surface through a phenomenon called “ Foliar transpiration ”. Some plants transpire via stems through a phenomenon termed “Cauline transpiration”. There are four types of transpiration:

Which is the correct definition of evapotranspiration?

n. 1. The combined processes of evaporation, sublimation, and transpiration of the water from the earth’s surface into the atmosphere. 2. The total amount of water transferred from the earth to the atmosphere. [evapo (ration) and transpiration .]

Why does transpiration slow down the cooling of a tree?

The cooling effect of a tree is due to the evaporation of water from its leaves. Transpiration slows down if the transpired water is not compensated by absorption from the soil. A lot of energy is released during transpiration. Plenty of unnecessary water is absorbed by the plants during the process. Transpiration in plants is a crucial process.
