1.	Question : How do neutral solutes move across the plasma membrane? Can the polar molecules also move across it in the same way? If not, then how are these transported across the membrane?
Answer» Solution :Neutral solutes may move across the MEMBRANE by the process of SIMPLE diffusion along the concentration gradient, i.e., from higher concentration to the LOWER. As the polar molecules cannot pass through the non-polar lipid bilayer, they require a carrier PROTEIN of the membrane to facilitate their transport across THEMEMBRANE.
