NEET Biology question
Not in NEET syllabus
Which of the following statements is/are true?
I. The apoplastic movement of water occurs exclusively through the cell wall without crossing any membranes. II. Solutes present in a cell (or in any solution) increase the free energy of water or water potential. III. The symplastic movement occurs from cell to cell through the plasmodesmata. IV. Membrane permeability depends on the membrane composition, as well as the chemical nature of the solute.
Solution
I is true — the apoplast pathway runs through the continuum of cell walls and intercellular spaces without crossing any membrane. II is false — dissolving a solute *lowers*, not raises, the free energy/water potential of water. III is true — symplastic movement
