The correct Answer is:
To determine the common characters found in chloroplasts and mitochondria, we will analyze each of the given options step by step. ### Step 1: Analyze Option I - Both involve in metabolism Both chloroplasts and mitochondria are indeed involved in metabolic processes. Chloroplasts are primarily responsible for photosynthesis, converting light energy into chemical energy, while mitochondria are involved in cellular respiration, generating ATP from glucose. **Conclusion**: This option is correct. ### Step 2: Analyze Option II - Photophosphorylation Photophosphorylation is a process that occurs specifically in chloroplasts during photosynthesis to produce ATP using light energy. Mitochondria do not perform photophosphorylation; instead, they generate ATP through oxidative phosphorylation. **Conclusion**: This option is incorrect. ### Step 3: Analyze Option III - Both are semi-autonomous organelles Both chloroplasts and mitochondria are considered semi-autonomous organelles because they contain their own DNA and ribosomes, allowing them to synthesize some of their own proteins independently of the cell's nuclear DNA. **Conclusion**: This option is correct. ### Step 4: Analyze Option IV - Both contain oxysomes Oxysomes, also known as ATP synthase complexes, are found in mitochondria, where they play a role in ATP production. While chloroplasts have similar structures called ATP synthase, the term "oxysomes" is not typically used to describe structures in chloroplasts. **Conclusion**: This option is incorrect. ### Final Summary: From the analysis: - Option I is correct. - Option II is incorrect. - Option III is correct. - Option IV is incorrect. Thus, the common characters found in chloroplasts and mitochondria are options I and III. ### Final Answer: The correct answer is: I and III. ---
