Expert Answer:

Chloroplasts and mitochondria are organelles found in the cells of living organisms and perform functions vital for the survival of the cell.

Structural similarities between mitochondria and chloroplast:

  • Have their own DNA.
  • Enclosed by two membranes (double membraned).
  • Involve oxygen and carbon dioxide in their processes.
  • Have fluids inside their structure.

Functional differences between mitochondria and chloroplast:



  • Found in almost all cells.
  • Found only in plants and few unicellular organisms.
  • Convert chemical energy (sugar) into another form of chemical energy (ATP).
  • Converts solar/light energy into chemical energy (sugar).


  • Process involved is cellular respiration which is composed of glycolysis, ETC, and oxidative phosphorylation
  • Process involved is photosynthesis which is composed of light reactions and Calvin cycle.
