Question

Select the matched ones.
(i) Guttation - Water loss in liquid phase.
(ii) Adhesion - Mutual attraction between water molecules.
(iii) Imbibition - Absorption of water by dry wood.
(iv) Hypotonic solution - Cells shrink.

• A. i, ii and iii only
• B. ii and iv only
• C. iii and iv only
• D. i and iii only

Answer 1

The correct option is D i and iii only

Loss of water in the form of water droplets from the pores of plants is called as guttation. Adhesion is the mutual attraction between unlike molecules that results in the sticking together of those molecules to one another. Imbibition is a type of diffusion in which water is absorbed by solid material like dry wood that results in an increase in volume. When a cell is placed in a hypotonic solution, there is more solute concentration in the cell than in the solution. Water moves from lower concentration of solute (solution) to higher concentration of solute (cell). This results in the swelling of cell.

Thus, the correct answer is option D.
