Which plant part primarily absorbs sunlight for photosynthesis?

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

Answer: (C)

The leaves of a plant are primarily responsible for absorbing sunlight for the process of photosynthesis. They contain specialized cells that possess chlorophyll, the green pigment that captures sunlight. During photosynthesis, the energy from the sunlight, along with carbon dioxide from the air and water from the soil, is used to produce glucose—a type of sugar that serves as food for the plant. This process also produces oxygen as a byproduct, which is released into the atmosphere.

While roots are important for absorbing water and nutrients from the soil, and stems provide support and transport materials between the roots and leaves, it is the leaves that play the critical role of capturing sunlight necessary for photosynthesis. Flowers, on the other hand, serve the purpose of reproduction rather than energy absorption, making leaves the key plant part in harnessing sunlight for this vital process.
