The theory of Endosymbiosis explains the origin of 
                                       chloroplasts and mitochondria and their double membranes.




      This concept postulates that chloroplasts and mitochondria 
              are the result of years of evolution initiated by the 
                endocytosis of bacteria and blue-green algae.
       According to this theory, blue green algae and bacteria 
           were not digested; they became symbiotic instead.   

             Endocytosis is when a substance gains entry 
         into a cell without passing through its cell membrane. 
                   A cell's plasma membrane invaginates 
                and fuses to lock foreign material inside. 
                 An intracellular vesicle is formed as a result.

                           The ribosomes of the inner structure (in chloroplasts and  mitochondria) 
                                                      resemble prokaryotic ribosomes.
