Cytology/ Cell Biology Discovery of cell diverted the attention of the biologist from morphology ( the study of form and gross structure of organism) to cytology (the study of cell) .For many years, cytology somehow remained confined to the structure of the cell as seen through a microscope. However, it now covers cell physiology (biosynthesis, energetics, motility, growth), cell reproduction and cell chemistry also , With these additions to its scope, cytology has been renamed cell biology. The cell biology may be briefly defined as the study of cell structure, chemical composition and function, A cell biologist generally describes fundamental processes common to all cells, Thus, cell biologist, in fact, the study of life.
