Which two plant structures are essential for photosynthesis and nutrient transport?

• A. Leaves and Roots
• B. Flowers and Stems
• C. Bark and Cambium
• D. Seeds and Leaves

Answer: (A)

The main idea here is how plants obtain energy and move nutrients. Leaves are the site of photosynthesis, where sunlight, carbon dioxide, and water are converted into sugars that feed the plant. Roots are responsible for taking in water and minerals from the soil, which are then transported through the plant to support growth and the photosynthetic process. So, pairing leaves with roots makes sense: leaves provide the energy-making function, while roots supply the essential raw materials (water and minerals) that enable that energy production and overall nutrient transport. Without leaves, photosynthesis can’t occur effectively; without roots, water and minerals can’t reach the leaves to power photosynthesis. The other options mix structures that aren’t primarily responsible for both functions. Flowers and stems are more about reproduction and support; bark and cambium are protective and growth tissues; seeds and leaves combine a reproductive structure with a photosynthetic one, but seeds don’t contribute to nutrient transport in the same direct way as roots do.
