Mitochondria and chloroplasts are semi-autonomous cell organelles, which contain their own DNA and protein synthesising machinery. They arise from pre-existing organelles and their functions are partially controlled by the nucleus of cell as well as the organelles themselves. WebBoth the chloroplast and the mitochondrion are organelles found in the cells of plants, but only mitochondria are found in animal cells. The function of chloroplasts and mitochondria is to generate energy for the cells in which they live.
