  • Page ID
  • The cell is the smallest and most basic unit of life and makes up all living organisms, whether unicellular or multicellular. In multicellular organisms, several cell types can interact to form specialized tissues and organs. Cells contain multiple organelles, or subcellular structures, that each have distinct structures and specific functions. Functions of these organelles are often dictated by the structure and are dependent on the location (tissue) of the cell and the physiological and disease status of the organism.
