Which statements is INCORRECT about this figure?


#Unit 6. System Physiology – Plant
  1. If the concentration of potassium chloride is higher in compartment A ([KCl]A > [KCl]B), potassium and chloride ions will diffuse at a higher rate into compartment B
  2. If membrane are more permeable to K+ tham to Cl-,  K+ will diffuse out of the cell (compartment A ) faster than Cl–, causing the cell to develop a negative electric charge with respect to the medium
  3. Diffusion of K+ would carry charges across the membrane until the membrane potential balanced the concentration gradient, Transport would then be at equilibrium, even though the concentration gradients were unchanged
  4. If membrane are more permeable to K+ tham to Cl-,  K+ will diffuse out of the cell (compartment A ) faster than Cl–, causing the cell to develop a positive electric charge with respect to the medium
