Photosynthesis produces which carbohydrate to feed the plant?

• A. Sugar
• B. Protein
• C. Lipids
• D. Vitamin

Answer: (A)

Photosynthesis uses light energy to convert carbon dioxide and water into a carbohydrate that the plant can use. The main product is glucose, a simple sugar. This sugar fuels cellular respiration to provide energy and can be stored as starch for later use, supporting growth and maintenance. That’s why the option describing a sugar is correct—the plant’s immediate carbohydrate product is a sugar form (glucose). Proteins, lipids, and vitamins arise from other biosynthetic processes and are not the primary carbohydrate output of photosynthesis.
