Which organelle is found only in plant cells (and not in animal cells) among the options below?

• A. Mitochondrion
• B. Chloroplast
• C. Ribosome
• D. Golgi apparatus

Answer: (B)

Verified step by step guidance

1. Identify the organelles listed in the options: Mitochondrion, Chloroplast, Ribosome, and Golgi apparatus.
2. Recall the functions and presence of each organelle in plant and animal cells. For example, mitochondria are found in both plant and animal cells and are responsible for energy production.
3. Understand that chloroplasts are the organelles responsible for photosynthesis and are unique to plant cells and some protists, but not found in animal cells.
4. Recognize that ribosomes, which synthesize proteins, and the Golgi apparatus, which modifies and packages proteins, are present in both plant and animal cells.
5. Conclude that the organelle found only in plant cells (and not in animal cells) among the options is the chloroplast.
