Answer: (C)

Verified step by step guidance

1. Understand the question: The problem asks us to identify which organelle is unique to plant cells and not found in animal cells. The options provided are Golgi apparatus, mitochondrion, chloroplast, and nucleus.
2. Review the function and presence of each organelle: The Golgi apparatus is involved in modifying, sorting, and packaging proteins and is found in both plant and animal cells. The mitochondrion, known as the powerhouse of the cell, is also present in both plant and animal cells. The nucleus, which houses genetic material, is a common feature of eukaryotic cells, including both plant and animal cells.
3. Focus on the chloroplast: Chloroplasts are specialized organelles found in plant cells and some protists. They are responsible for photosynthesis, a process that converts light energy into chemical energy stored in glucose. Chloroplasts contain the pigment chlorophyll, which gives plants their green color.
4. Recognize the key distinction: Chloroplasts are unique to plant cells and are not found in animal cells. This is because animals do not perform photosynthesis and therefore do not require chloroplasts.
5. Conclude the reasoning: Based on the analysis, the correct answer is chloroplast, as it is the only organelle in the list that is exclusive to plant cells.
