This course, together with the Animal Body courses and the Biology of Populations, Species and Ecosystems course, forms a series examining the levels of organisation of life. Biology of Cells or cell biology introduces the basic unit of life: the cell; and its constituent structures and cycle in their exposure to molecular biology. Students will learn the interplay of morphology and functions in animal and plant cells in molecular terms. The main objective of this course is to let students appreciate the intimate relationship between “structure” and “function” in biology: how specialized cellular structures are evolved to accommodate and facilitate particular biochemical reactions and how the defects in cellular structures can lead to certain disease states.
