Similarities of mitochondrial plastid by table?
Similarities between Mitochondria and Plastids:
Mitochondria and plastids are both membrane-bound organelles found in eukaryotic cells. Despite their differences in structure and function, they share several similarities:
  • DNA and Ribosomes: Both mitochondria and plastids contain their own DNA and ribosomes, allowing them to carry out some of their own protein synthesis independently of the cell's nucleus.
  • Energy Production: Both organelles are involved in energy production. Mitochondria are known as the powerhouse of the cell, producing ATP through aerobic respiration. Plastids, on the other hand, are involved in processes like photosynthesis in plant cells, producing glucose as a form of energy.
  • Double Membrane: Both mitochondria and plastids have a double membrane structure. This double membrane helps in compartmentalizing the organelles and regulating the passage of molecules in and out of the organelles.
  • Endosymbiotic Theory: Both organelles are believed to have originated from endosymbiotic relationships. According to the endosymbiotic theory, mitochondria and plastids were once free-living prokaryotic organisms that were engulfed by a primitive eukaryotic cell and formed a symbiotic relationship over time.
  • Role in Cell Metabolism: Both mitochondria and plastids play crucial roles in cell metabolism. Mitochondria are involved in processes like the citric acid cycle and oxidative phosphorylation, while plastids are involved in processes like carbon fixation and synthesis of organic compounds.


In conclusion, mitochondria and plastids may have distinct functions within a cell, but they also exhibit several key similarities in terms of structure, function, and evolutionary history. These similarities highlight the interconnectedness of different organelles within a cell and their essential roles in cellular processes.
