Which of the following organelles are found only in plant cells?

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

Answer: (D)

Verified step by step guidance

1. Begin by identifying the organelles listed in the problem: Nucleus, Mitochondria, Ribosomes, and Chloroplasts.
2. Understand that plant cells and animal cells share many organelles, such as the nucleus, mitochondria, and ribosomes, which are found in both types of cells.
3. Recognize that chloroplasts are unique to plant cells and some algae, as they are involved in photosynthesis, converting light energy into chemical energy.
4. Recall that chloroplasts contain chlorophyll, the pigment responsible for capturing light energy, which is a key feature distinguishing plant cells from animal cells.
5. Conclude that chloroplasts are the organelles found only in plant cells, as they are essential for the process of photosynthesis, which does not occur in animal cells.
