Introduction:

  • A cell is the unit of a living thing. 
  • A living thing can be made up of one cell like a bacterium of many cells like a human. Irrespective of the number of cells, living things are referred to as organisms. 
  • Hence, the cell is the basic unit of an organism.
  • A cell can be defined as the basic structural and functional unit of life. 
  • It is called the structural unit because it forms the body/structure of the organisms. 
  • It is called the functional unit because each cell is capable of performing the essential metabolic functions.

  • In 1674, the documentation of live cells was made by  Anton van Leeuwenhoek, who observed bacterial cells and algal cells.
