Sugar molecules move across the plasma membrane until the cell has enough energy to grow in size and divide.

Water molecules move across the plasma membrane until solute concentrations are equal on both sides of the membrane.

Ions move across the plasma membrane until the inside of the cell has a higher concentration of positive charges.

Enzymes move across the plasma membrane until the cell has completed metabolism.

The concentration of water is greater outside the cell than inside the cell.

The temperature of water in the vacuole is higher than the temperature of its environment.

The concentration of water inside the cell is the same as the concentration outside the cell.

The temperature of water in the vacuole is lower than the temperature of its environment.
