Which of the following combination is an example of self replicating organelles?
Correct answer: C. Mitochondria Chloroplast
- A. Mitochondria Ribosomes
- B. Mitochondria Nucleus
- C. Mitochondria Chloroplast
- D. Mitochondria Vacuole
Explanation
Mitochondria and chloroplasts contain their own DNA and ribosomes, allowing them to produce some proteins and replicate independently within the cell. This semi-autonomous nature supports the endosymbiotic theory. Ribosomes do not self-replicate as organelles, and vacuoles lack their own genetic system, so option a is a common mistake.

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.
