Question

Mention four purposes for which the plants need water.

Answer 1

1. Photosynthesis: Water is used as a raw material for the synthesis of food by green leaves.
2. Transportation: Water carries various compounds in solution from the roots to the upper parts of the plant, or from the leaves to other sections.
3. Transpiration: During transpiration, a large amount of water is released as water vapour to cool the plant in hot conditions and create a suction force.
4. Turgidity: Water also provides turgidity, which is required for the rigidity of plant tissue.
