Science Education: Cell Biology
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?
