Which of the following statements are true for mitochondria and chloroplasts?A. ATP synthesis is seen in bothB. The outer membrane has more surface area in bothC. Circular naked DNA, RNA, and 70 ribosomes are seen in bothD. Oxidative phosphorylation occurs in both
Correct answer: C. A and C
- A. A and B
- B. B and C
- C. A and C
- D. A and D
Explanation
ATP synthesis is seen in both chloroplasts and mitochondria. The inner membrane of mitochondria is folded to increase surface area.Both mitochondria and chloroplasts have small, circular DNA, all kinds of RNA and 70S ribosomes.Oxidative phosphorylation takes place only in mitochondria.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
