Discuss biological and industrial importance of osmosis.

1.	Discuss biological and industrial importance of osmosis.
Answer» Hint: The process of osmosis is of immense biological and industrial importance as is evident from the following examples : (i) Movement of water from soil into plant roots and subsequently into upper portion of the plant is partly due to osmosis. (ii) Preservation of meat against bacterial action by adding salt. (iii) Preservation of fruits against bacterial action by adding sugar. Bacterium in canned fruit loses water through the process of osmosis, shrivels and dies. (iv) Reverse osmosis is used for desalination of water.
