Which macromolecule is primarily produced during photosynthesis and serves as food for plants?

• A. Carbohydrates
• B. Nucleic acids
• C. Lipids
• D. Proteins

Answer: (A)

Verified step by step guidance

1. Understand the process of photosynthesis: Photosynthesis is the process by which plants convert light energy into chemical energy stored in molecules. This occurs in the chloroplasts of plant cells.
2. Identify the primary product of photosynthesis: During photosynthesis, carbon dioxide (CO₂) and water (H₂O) are converted into glucose (C₆H₁₂O₆), a type of carbohydrate, using sunlight and chlorophyll as catalysts.
3. Recognize the role of carbohydrates: Carbohydrates, such as glucose, are the primary macromolecules produced during photosynthesis. They serve as an energy source and structural material for plants.
4. Eliminate other options: Nucleic acids, lipids, and proteins are not directly produced during photosynthesis. These macromolecules are synthesized later using the energy and carbon skeletons provided by carbohydrates.
5. Conclude that carbohydrates are the correct answer: Based on the process of photosynthesis and the role of glucose, carbohydrates are the macromolecules primarily produced and used as food for plants.
