Question

Land plants grow in soils which possess an osmotic concentration

• A. Hypotonic in relation to cells
• B. Hypertonic in relation to cells
• C. Isotonic in relation to cells
• D. Ultratonic in relation to cells

Answer 1

The correct option is A 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.

If soil solution is hypotonic water will flow out from soil to roots.
