About cell biology
Cell biology studies cells, the tiny units every living thing is made of, and the parts inside them.
Cell biologists study organelles, membranes and the cytoskeleton, and how cells grow, divide, communicate and die.
The field spans organelle function, protein trafficking, cell mechanics and signaling, and the origin of complex cells through endosymbiosis.
