Neutral solutes do not carry any charge because they move across the plasma membrane through osmosis. while polar molecules are charged molecules so they cannot pass through the non-polar membrane. To cross the non-polar membrane they require a carrier protein that facilitates its transport inside the cell. If this transport takes place against the concentration gradient, it will require energy in the form of ATP.
