Which macromolecule is synthesized as a result of photosynthesis and serves as a primary energy-storage product in plants?

• A. Carbohydrates (e.g., glucose and starch)
• B. Nucleic acids (DNA and RNA)
• C. Proteins (polypeptides)
• D. Lipids (triglycerides)

Answer: (A)

Verified step by step guidance

1. Understand that photosynthesis is the process by which plants convert light energy into chemical energy stored in organic molecules.
2. Recall that the general equation for photosynthesis produces glucose, a type of carbohydrate, from carbon dioxide and water using sunlight.
3. Recognize that carbohydrates, such as glucose, serve as the primary energy-storage molecules in plants because they can be easily broken down to release energy.
4. Note that while nucleic acids, proteins, and lipids are important macromolecules, they are not the main products synthesized directly by photosynthesis for energy storage.
5. Conclude that carbohydrates (e.g., glucose and starch) are the macromolecules synthesized as a result of photosynthesis and serve as the primary energy-storage products in plants.
