Cells in potatoes are plant cells. Cells in potatoes do not contain chloroplasts.
What is the function of chloroplasts?
How to approach this question
Think about where you find chloroplasts (usually in the green parts of a plant, like leaves). What important process happens in these parts, and what do chloroplasts do in that process?
Full Answer
To absorb light for photosynthesis.
Chloroplasts are organelles found in the cells of green plants and algae. They contain the green pigment chlorophyll, which absorbs light energy from the sun. This captured light energy is then used to power the process of photosynthesis, where carbon dioxide and water are converted into glucose and oxygen. Therefore, the primary function of chloroplasts is to be the site of photosynthesis.
Common mistakes
✗ Just saying "they are green" or "contain chlorophyll" without stating the function.\n✗ Confusing photosynthesis with respiration.
