Question

How is transpiration measured?

Answer 1

Hint: Transpiration is the passage of water through a plant that results in the evaporation of water from the leaves. Water evaporates through the aerial portions of plants, such as shoots, leaves, and flowers. The water taken up and lost by the plant is a crucial feature that is maintained at a specific pace depending on the plant's surroundings.

Complete answer:
Water is a crucial component that plants require to carry out numerous functions, particularly photosynthetic processes. Water is taken up by the roots from the earth and carried to the leaves via various conducting tissues. The plant uses some water during this process, but the majority of it is lost to the environment through transpiration.
Transpiration is the process of surplus water being removed from sections of the shoot system that are above ground level. The process of transpiration occurs when water is lost from the leaves and shoots in the form of water vapours.
The rate of transpiration is determined by the stomatal holes' opening and shutting. The rate of transpiration can be influenced by a variety of environmental conditions. A potometer is used to determine the rate of transpiration.

The rate of transpiration, which is proportional to the amount of water taken up by the plant, is measured using a device named a photometer.

Note:
Transpiration is a common occurrence in plants, and it occurs when the stomata open and close on a regular basis, releasing water vapour from the plant's surface. The distance travelled by an air bubble in a given time inside a capillary tube is used to calculate the rate of transpiration. A photometer is a device that measures the rate of transpiration in plants.
