WebMitochondria are the "powerhouses" of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They're responsible for capturing light energy to make sugars in photosynthesis. Mitochondria and chloroplasts likely began as bacteria that were engulfed by larger cells (the ...
