ABSTRACT

WHAT IS CELL BIOLOGY? Cell biology is the study of cellular form and function at a microscopic and biochemical level. In contrast, molecular biology is concerned with investigating the structure and function of the biological macromolecules which comprise cells. Cell biology draws upon microscopy, biochemistry, immunology and to some extent molecular genetics. The topics that cell biology encompasses are: chemistry and function of biomolecules, cells and their organelles, movement of molecules across membranes, mitosis and meiosis, metabolism, photosynthesis, and cell signaling. Some cell biologists may have additions to this list.
