How do neutral solutes move across the plasma membrane? Can the polarmolecules also move across it in the same way? If not, then how are thesetransported across the membrane?

Question

Neutral solutes move across the membrane by the process of simple diffusion along the concentration gradient which is from higher concentration to lower concentration. Polar molecules cannot move across the membrane in the same way. They require a carrier protein of the membrane to facilitate their transport.
