The Detective Work of Biology

Every great biological discovery started with careful observation and experimentation. When Robert Hooke first observed cells in cork using his primitive microscope in 1665, he was doing exactly what you'll learn in these practicals - using scientific methods to unlock the secrets of life.

The three Required Practicals in Cell Biology will give you the essential skills every biologist needs: precise observation, controlled experimentation, and critical analysis of results.
