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

Answer: (A)

Verified step by step guidance

1. Identify the unique features of plant cells compared to animal cells. Plant cells have certain structures that are not found in animal cells.
2. Consider the function of chloroplasts. Chloroplasts are organelles that conduct photosynthesis, a process unique to plants and some algae.
3. Evaluate the presence of mitochondria, ribosomes, and the nucleus in both plant and animal cells. These structures are common to both types of cells.
4. Understand that chloroplasts are responsible for converting light energy into chemical energy, a function not needed in animal cells.
5. Conclude that chloroplasts are the cell structures found in plant cells but not in animal cells, as they are essential for photosynthesis.
