The red cell of vertebrates is a remarkably effective device for the transport of oxygen to other cells. Many workers seek to elucidate the intricate molecular structure of its surface ...

Red blood cells are disc-shaped cells with no nucleus. They are very small but their flattened shape gives a relatively large surface area which allows rapid diffusion of oxygen.

Within every cell (except red blood cells) is a nucleus -- a sphere-like structure separated from the rest of the cell by a membrane. The nucleus acts as the cell's control center, regulating its ...
