Plant cells have several internal compartments, each of which can differ in its ionic composition. The cytosol and the vacuole are the most important intracellular compartments that determine the ionic relations of plant cells, Ion concentrations in the cytosol and the vacuole are controlled by passive (dashed arrows) and active (solid arrows) transport processes
  

Which of the following statement INCORRECT from the above figure;

#Unit 6. System Physiology – Plant
  1. Potassium is accumulated passively by both the cytosol and the vacuole, except when extracellular K+ concentrations are very low, in which case it is taken up actively
  2. All the anions are taken up actively into the cytosol.
  3. Calcium is actively transported out of the cytosol at both the cell membrane and the vacuolar membrane, which is called the tonoplast
  4. Sodium is pumped passively out of the cytosol into the extracellular spaces and vacuolar membrane
