The process of osmosis would explain the net movement of water into a cell if the percentage of: 1) Water was 90% inside the cell and 95% outside the cell 2) Protein was 30% inside the cell and 35% outside the cell 3) Water was 95% inside the cell and 90% outside the cell 4) Water and protein were equal inside and outside the cell

Osmosis describes the movement of a solvent (in this case, water) from areas of low solute concentration to areas of high solute concentration, seeking to balance the two regions.

We can eliminate #4 based on this principle. If water and protein are equal, there is no net movement in or out of the cell.

We're assuming that whatever is not water must be the solute. The water wants to go to the place where there is less water;

  • In #1, there is less water inside the cell
  • In #2, there is less water outside the cell
  • In #3, there is less water outside the cell

Water will go into cell #1, and out of cells #2 and 3.

Which cell has net movement of water inside the cell? Cell #1
