Cell biology is the study of the structure, development, and functions of cells, both prokaryotic and eukaryotic. The structure of cells include the structure of cellular compartments such as chromosomes, mitochondria, chloroplasts, cell walls, and more, and the structure of cell surface components such as receptors. Cellular development includes the processes of cell division and differentiation. That is, the processes that give rise to how a cell multiplies, divides, and yields new cells that grow to carry out their proper and given function. Functions of cells include processes of cell communication, gene expression, mobility, division and differentiation. Each of these is a unique and complex component, the sum of which describes the exciting field of cell biology.
