• C. Lysosomes
• D. Chloroplasts

Answer: (D)

Verified step by step guidance

1. Identify the key organelles listed in the problem: Ribosomes, Mitochondria, Lysosomes, and Chloroplasts.
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. Mitochondria are also present in both plant and animal cells and are the sites of cellular respiration, producing energy.
4. Lysosomes are more common in animal cells and are involved in digestion and waste removal, but they are generally absent or rare in plant cells.
5. Chloroplasts are unique to plant cells and some protists; they carry out photosynthesis, converting light energy into chemical energy, and are not found in animal cells.
