A cell from the lining of the small intestine is placed in a dilute solution. The cell swells.
Which statement correctly links the water potentials on either side of the cell membrane to this change?
The solution has a higher water potential than the cell, so water moves out of the cell through the partially permeable membrane.
The solution and the cell have equal water potentials, so water moves into the cell through the partially permeable membrane.
The solution has a higher water potential than the cell, so water moves into the cell through the partially permeable membrane.
The solution has a lower water potential than the cell, so water moves into the cell through the partially permeable membrane.
