 - 
  
  she argued that eukaryotic cells originated as communities of interacting entities
 - 
  
  she studied the structure of cells
 - 
  
  in 1981, Margulis published Symbiosis in Cell Evolution. it told how new mitochondria and plastids are formed only through a process similar to binary fission.

  The endosymbiotic theory concerns the mitochondria, plastids and possibly other organelles of eukaryotic cells.
 - 
  
  in 1999 she is awarded with the William Procter prize for scientific achievement. It is awarded to a scientist who has made an outstanding contribution to scientific research

  She helps discover secondary symbiosis. Secondary symbiosis occurs when the product of primary endosymbiosis is itself engulfed and retained by another free living eukaryote
