Science Education: Cell Biology

A scanning electron microscope picture of a nerve ending. Credit:Tina Carvalho, University of Hawaii at Manoa.Understanding the structure and function of cells and their many parts, in health and in disease—that's cell biology. Studies in cell biology focus on questions like:

  • How do cells move, communicate, divide and ultimately die?
  • How are cellular components made and maintained?
  • What tools do we need to study cells up close and in real time?

Follow the links below to learn more about cell biology, including recent discoveries, and read profiles of researchers working in this field.
