WebThis clever design makes cell membranes moist on their surfaces but watertight in the middle. Small non-polar molecules like oxygen and carbon dioxide can drift right through the membrane but anything polar or large is going to be stuck, and will need to be actively transported through one of the cell's gates. WebPolar molecules can easily interact with the outer face of the membrane, where the negatively charged head groups are found, but they have difficulty passing through its hydrophobic core. Water molecules, for instance, cannot cross the membrane rapidly (although thanks to their small size and lack of a full charge, they can cross at a slow rate).
