Question

Plants donot use all water the absorb from soil much of its given off by transpiration why then do plants absorb so much water

Answer 1

Transpiration is the loss of water from a plant in the form of water vapour. Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem. In the leaves, small pores allow water to escape as a vapour. But they absorb too much water for their growth, for making food and the process of photosynthesis.

Answer 2

Explanation:

Plants absorb minerals and nutrients from the soil in liquid form through Osmosis so they have to absorb much water even to take up small quantities of these nutrients. The excess of water is of no use for the plant so it gets rid of it through transpiration.
