Biology 2014 JAMB Past Questions - Question 19: Water in plants is removed as water vapour through the process of

Correct Answer

D

Explanation

. Water is lost through the stomata the leaves and lenticels of the stems. Diffusion is the random movement of molecules or ions from solution of high osmotic concentration solution of low osmotic concentration until the molecules ions are evenly distributed .Osmosis is the movement of solve (water molecules) from solution low osmotic concentration of so to solution of high osmosis concentration of solute through" semi permeable membrane and' movement continues until the solutions are of equal concentration (isotonic) or it is the movement solvent from solution where water in higher concentration to solution where water is in lower concentration through a semi permeable membrane until equilibrium is reached.
