Leaves primarily function to:

• A. Absorb sunlight to manufacture plant sugars through photosynthesis
• B. Absorb nutrients from soil
• C. Anchor the plant in soil
• D. Attract pollinators

Answer: (A)

Leaves primarily function to capture sunlight and drive photosynthesis, turning light energy into sugars that fuel the plant’s growth. Chlorophyll in leaf cells absorbs light and, through the chloroplasts, powers the light-dependent reactions that produce ATP and NADPH. These energy carriers feed the Calvin cycle, which fixes carbon dioxide into organic sugars such as glucose. The broad surface area of leaves and their stomata for gas exchange make them ideal for this process, supplying the energy and building blocks the rest of the plant needs. While roots absorb water and minerals and stems provide support, and flowers attract pollinators, the main job of leaves is to synthesize sugars from light.
