Question

What is transpiration? Why do plants do it ?

Answer 1

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. ... Transpiration also cools plants, changes osmotic pressure of cells, and enables mass flow of mineral nutrients and water from roots to shoots.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

Question:-

What is transpiration and why do plants do this?

Answer:-

• Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.
• It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis. Plants need to cool themselves for several reasons. The stomata (pores) must open to take in carbon dioxide for photosynthesis (especially important on mornings of sunny days).
