Which of the following organelle is involved in the release of oxygen?
Correct answer: B. Chloroplast
- A. Mitochondria
- B. Chloroplast
- C. Ribosomes
- D. Both A and B
Explanation
The correct answer is Chloroplast, which is responsible for the process of photosynthesis. In this process, chloroplasts convert light energy into chemical energy, releasing oxygen as a byproduct. Mitochondria, on the other hand, are involved in cellular respiration, where they utilize oxygen to produce energy and release carbon dioxide, not oxygen. Ribosomes are only involved in protein synthesis, with no role in oxygen production or release. Finally, the option Both A and B is misleading because it incorrectly suggests that both mitochondria and chloroplasts release oxygen, which is not true.
