Polarity describes the uneven distribution of cell organelles and components within cells, with some parts concentrated on one side versus the other. Specifically, polarity refers to cell membrane selective permeability, where the membrane is permeable to some substances but not others depending on location. This polarized distribution of molecules and structures allows cells to perform specialized functions and communicate with other cells.
