Which structures are specialized organs that make food through photosynthesis?

• A. Leaves
• B. Flowers
• C. Roots
• D. Stems

Answer: (A)

Leaves are the structures that perform photosynthesis. In the leaves, cells contain chloroplasts with chlorophyll that capture light energy to convert carbon dioxide and water into glucose, the plant’s food, while releasing oxygen. The broad, flat shape provides a large surface area to absorb light, and stomata on the underside regulate gas exchange—bringing in carbon dioxide and letting oxygen and water vapor exit. Veins supply water from the roots via xylem and carry the produced sugars away through phloem to other parts of the plant. Roots and stems support the plant and transport resources, but leaves are specialized for making food through photosynthesis.
