Course overview
Cell biology focuses on the structure, function, and behaviour of cells, the building blocks of all living organisms. This course introduces learners to cellular components such as membranes, organelles, and the cytoskeleton, while exploring essential processes like cell division, signalling, and energy production. Students will also learn how cells interact to form tissues and how cellular dysfunction leads to disease. By bridging molecular biology with physiology, cell biology provides critical insights into life’s complexity and lays the foundation for biomedical and biotechnological advances.
