Transpiration: Loss of water vapor from leaves and other parts of plants through stomata.
Explanation
Transpiration is a vital process in plants where water absorbed by roots is transported to leaves and released as vapor. This process helps in cooling the plant, transporting nutrients, and maintaining water balance. In India's tropical climate, plants transpire heavily during hot months. The rate of transpiration depends on temperature, humidity, wind, and light intensity. Together with evaporation from soil, it forms the water cycle.
Example
In a potted plant kept near a sunny window, you can observe water loss through transpiration by placing a transparent plastic bag over the leaves and seeing water droplets form inside.
Frequently Asked Questions
What is the difference between transpiration and evaporation?
Transpiration is loss of water from plants through stomata, while evaporation is loss of water from soil and water bodies. Together they form transpiration.
Why is transpiration important for plants?
Transpiration helps absorb and transport water and minerals from roots to leaves, cools the plant, and maintains turgidity in cells.
