Abstract
Most single animal cells have an internal vector that determines where recycling membrane is added to the cell's surface. Because of the specific molecular composition of this added membrane, a dynamic asymmetry is formed on the surface of the cell. The consequences of this dynamic asymmetry are discussed, together with what they imply for how cells move. The polarity of a single-celled embryo, such as that of the nematode Caenorhabditis elegans, is explored in a similar framework.
