• A. Ribosomes
• B. Chloroplasts
• C. Mitochondria
• D. Lysosomes

Answer: (B)

Verified step by step guidance

1. Identify the organelles listed in the problem: Ribosomes, Chloroplasts, Mitochondria, and Lysosomes.
2. Recall the functions and presence of each organelle in plant and animal cells. Ribosomes are found in both plant and animal cells and are responsible for protein synthesis.
3. Understand that mitochondria are also present in both plant and animal cells and are the sites of cellular respiration.
4. Recognize that lysosomes are primarily found in animal cells and are involved in digestion and waste removal.
5. Know that chloroplasts are unique to plant cells and other photosynthetic eukaryotes, where they carry out photosynthesis, converting light energy into chemical energy.
