Do both mitochondria and chloroplasts have their own DNA?

Yes. Both are semi-autonomous organelles with their own circular DNA and 70S ribosomes, which supports the endosymbiotic theory of their origin.

Which organelle is the powerhouse of the cell?

Mitochondria are called the powerhouse of the cell because they produce most of the cell’s ATP through cellular respiration.

Difference Between Mitochondria and Chloroplast

Mitochondria and chloroplasts are both double-membrane, energy-related organelles, but they handle energy in opposite directions.

In short

Mitochondria release energy by breaking down glucose in cellular respiration (present in all aerobic cells); chloroplasts trap light energy to make glucose in photosynthesis (present only in green plants and algae).

Mitochondria vs Chloroplast - Comparison Table

Basis	Mitochondria	Chloroplast
Function	Cellular respiration (releases energy)	Photosynthesis (traps energy)
Found in	Plant and animal cells	Green plant and algal cells only
Pigment	Absent	Chlorophyll (green)
Inner folds	Cristae	Thylakoids (grana)
Gas exchange	Uses O₂, releases CO₂	Uses CO₂, releases O₂
Energy conversion	Chemical (glucose) → ATP	Light → chemical (glucose)
