What do plants need for photosynthesis?
Answer and explanation
Correct answer: Sunlight
Photosynthesis is the process by which green plants prepare food. Light energy is needed to drive this process, and sunlight is the usual natural source of that energy. Plants also use water and carbon dioxide, while chlorophyll helps capture light. The food made by photosynthesis supports plant growth and supplies energy to many organisms through food chains.
Option A is correct because sunlight provides the energy required for photosynthesis. Plastic, cement, and smoke are not ingredients that enable plants to make food. Although sunlight alone is not the complete requirement, it is the only relevant need listed among the choices. The question therefore correctly links sunlight with plant food production.
