Question

What is transpiration ?
​

Answer 1

Answer

Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is 'pulled' into the leaves.

This is transpiration. It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis. ... Transpiration is an evaporative cooling system that brings down the temperature of plants, but since it leads to water loss, it must be accurately regulated.

Answer 2

Answer:

Transpiration is the process of releasing water in the form of water vapour.

Explanation:

• The evaporation of excess water from a leaf's surface through the stomata is known as transpiration.
• Transpiration has a cooling effect, which protects the plant from the scorching sun.
• The evaporation of water from leaves creates a suction force that can lift water from the tree's roots to the top.
