Which cell organelles have their own DNA and Ribosomes ?

The correct answer is Mitochondria and Plastids.

Key Points

• Both mitochondria and chloroplasts contain their own DNA and ribosomes.
• Both plant cells and animal cells possess mitochondria. It has its own DNA and plays a met role in the synthesis of enzymes and the production of energy.
• Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.
  • Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
• Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process.
  • By doing so, they sustain life on Earth. Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process.
