The two cell organelles involved in energy conversion are chloroplasts and mitochondria.
Chloroplasts are found plants. They are the photosynthesizing organelles of all photosynthetic eukaryotes.
Mitochondria are found in both plants and animals. It converts food such as sugars into the chemical ATP, the main source of energy for cell work.
Both organelles are said to evolve through a process called "endosymbiosis".
