Which pair of structures best demonstrates that plant cells have functions different from animal cells?

• A. Mitochondria and ribosome
• B. Nucleus and endoplasmic reticulum
• C. Cell wall and chloroplast
• D. Golgi apparatus and lysosome

Answer: (C)

Verified step by step guidance

1. Understand the question: The problem asks which pair of structures best demonstrates that plant cells have functions different from animal cells. This requires identifying structures unique to plant cells and their roles.
2. Step 1: Recall that plant cells have unique structures not found in animal cells. These include the cell wall and chloroplasts, which are essential for plant-specific functions like photosynthesis and structural support.
3. Step 2: Compare the options provided. Mitochondria and ribosomes are found in both plant and animal cells, so they do not demonstrate unique plant functions. Similarly, the nucleus and endoplasmic reticulum are common to both cell types.
4. Step 3: Evaluate the cell wall and chloroplasts. The cell wall provides rigidity and protection, a feature absent in animal cells. Chloroplasts are responsible for photosynthesis, a process unique to plants and some protists.
5. Step 4: Conclude that the correct answer is 'Cell wall and chloroplast,' as these structures highlight the unique functions of plant cells compared to animal cells.
