   • Why would prokaryotes need different shapes?
   • What other ways to determine bacteria species are used in medicine?

Answer 1

Endosymbiotic theory is regarding the evolution of eukaryotic cell Eukaryotic cells are evolved by multiple cells joined together into one. They began to live in symbiotic relationships. The theory explains that how organisms lived together. An endosymbiont is one organism that lives inside of another one. The most common mitochondria and chloroplasts have their own dna they were once free living prokaryotic cells or parasite which were engulfed by phagocytosis rather than being eaten or killed they developed a relationship between each other called symbiotic. Host cell provide space to live organelles in exchange provide energy by respiration or photosynthesis .
