Which statement below best describes how a cell responds to its external environment?

• The difference in concentration of solids in a cell’s external environment has no effect on how water moves into and out of a cell.

• If the concentration of solids in the cell’s external environment is greater than the internal environment, water passes out of the cell.

• If the concentration of solids in the cell’s external environment is less than the internal environment, the water passes into the cell.
