In 1838 the cell theory was proposed by two German scientists Schleiden and Schwann. 

It describes the basic concept of how life on Earth functions .

The principles of cell theory are:  

  • All the living organisms are composed of cells .  
  • The living organisms could be made up of one or more cells .  
  • The new cells arise from pre-existing cells through the process of cell division
  • The cells in different organisms vary in the number, shape and size .
