Ribosomes and DNA are also present in_________?
Correct answer: A. mitochondria
- A. mitochondria
- B. golgi complex
- C. endoplasmic reticulum
- D. lysosomes
Explanation
Mitochondria contain their own circular DNA and 70S ribosomes, reflecting their evolutionary origin from bacteria. The endoplasmic reticulum may appear linked with ribosomes, so students may choose it, but it does not normally contain its own DNA.

About Cytoplasmic Organelles
Cytoplasmic organelles are the specialized structures suspended in cytoplasm, including mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles and centrosomes. Questions compare their structures and functions in animal and plant cells, including chloroplasts and the role of the endomembrane system in transport and secretion.
