Cell Biology: This is the branch of biology that deals with the study of morphological, organizational, physiological, biochemical, genetical, developmental pathological and evolutionary aspects of cell and its components. Cell biology is a scientific discipline which studies cells - their physiological properties, the organelles they contain, their structure, their life cycle, interactions with their environment, division or death.
Cell biology research encompasses both the single-celled organisms like bacteria or protozoa, as well as the many specialized cells in multicellular organisms like humans. Research in cell biology is closely related to biochemistry, genetics, immunology, developmental biology or molecular biology.
