Difference Between Mitochondria and Chloroplasts: The following are the points of difference between Mitochondria and Chloroplasts. Mitochondria Chloroplasts Mitochondria are colourless cell organelles. Chloroplasts are green cell organelles. Mitochondria occur in plants, animals, protists and fungi. Chloroplasts occur in plants and some protists. The organelles are found in all cells of aerobic organisms. They are present in only green cells exposed to light. Mitochondria are generally cylindrical in outline. Chloroplasts of higher plants are discoid in outline. They have various shapes in lower organisms. The inner membrane shows involutions called cristae. The inner membrane develops involutions called thylakoids or lamellae. … Continue reading Difference Between Mitochondria and Chloroplasts
