What is Cells & Life?
Cells are the basic units of life. All living things are made of cells, from bacteria to humans. Understanding cell structure and how cells work is fundamental to all biology—it explains growth, reproduction, energy, and the diversity of life itself.
In this area, you'll explore plant and animal cell structures, organelles and their functions, and cell division. Cell biology provides the foundation for understanding organisms, ecosystems, and all biological processes.
