Q. Read the following statement and choose the correct one from the codes given below I. The apoplastic movement of water takes place exclusively through intercellular spaces and cell wall without crossing any membrane II. Symplastic movement occurs from cell to cell through plasmodesmata, $i.e$., adjacent cells are connected through plasmodesmata III. Permeability of a membrane depends on its composition and chemical nature of the solute IV. Solutes present in a cell increases the free energy of the water or water potential
A) I, II and III
B) I, II and IV
C) II and IV
D) I and IV
Explanation
Addition of solutes in a system or cell decreases the energy of water. Pure water has the maximum diffusion pressure. Water potential or chemical potential of pure water is the difference in the free energy per unit molal volume of water in a system in reference to pure water at normal temperature and pressure
