Question

Land plants grow in soils that possess an osmotic concentration:

• (A) Hypotonic in relation to cells
• (B) Hypertonic in relations to cells
• (C) Isotonic in relation to cells
• (D) Ultrotonic in relation to cells

Answer 1

The Correct Option is A

Explanation:
Land plants grow in soils which possess an osmotic concentration. An osmotic concentration is hypotonic in relation to cells. Land plants require water for physiological processes. They gain it from the soil by through endosmosis. Endosmosis can occur only when soil solution is hypotonic in relation to cells. Hypotonic solution is the solution which posses less concentration of solute. Solvent always flows out from high concentration of solvent to low concentration.Hence the correct option is (A).
