Which part of the plant primarily conducts photosynthesis?

Leaves are the primary sites of photosynthesis in plants due to the presence of chlorophyll, the green pigment that captures light energy from the sun. The structure of leaves, with their broad surface area and numerous chloroplasts, allows them to maximize light absorption and gas exchange. During photosynthesis, leaves convert carbon dioxide and water into glucose and oxygen, utilizing sunlight as the energy source. This process is crucial for the plant's growth and energy needs and serves as the foundation of the food chain for other organisms.

Roots are primarily involved in water and nutrient absorption from the soil, while xylem is responsible for transporting water and dissolved minerals from the roots to the rest of the plant. Flowers play a key role in reproduction, attracting pollinators, and facilitating seed production but do not conduct photosynthesis.
