Which statement correctly describes photosynthesis?

• A. Heterotrophs convert solar energy into chemical energy
• B. All organisms perform photosynthesis
• C. Autotrophs convert solar energy into chemical energy
• D. Mitochondria produce solar energy

Answer: (C)

Photosynthesis is the process by which autotrophs convert light energy from the sun into chemical energy stored in organic molecules. Autotrophs, such as plants, algae, and certain bacteria, use light energy to convert carbon dioxide and water into sugars, storing energy in chemical bonds. Heterotrophs don’t perform photosynthesis—they rely on autotrophs for energy. Not all organisms can photosynthesize, so this isn’t a universal trait. Mitochondria are involved in cellular respiration, not capturing light energy, so they don’t produce solar energy. Therefore, the statement that autotrophs convert solar energy into chemical energy best describes photosynthesis.
