MEMBRANES ORGANIZE CELLULAR COMPLEXITYMembranes are critical for organized and efficient cell function.
CELLS COMMUNICATE
Cells communicate through signals, aided by pathways made mostly of proteins. A cell's response depends on the signal itself, as well as the cell type.

WHEN CELL COMMUNICATION GOES WRONGCell communication can be disrupted in a number of ways, sometimes resulting in disease.
CELLS IN PERSPECTIVE
In 1665, Robert Hooke coined the term cell to describe the structures he could see in cork with some of the first microscopes. Since then, technology has given us an increasingly complex view of the basic unit of life.
