The process by which plants make food is called what?

• A. Fermentation
• B. Respiration
• C. Transpiration
• D. Photosynthesis

Answer: (D)

Plants make their own food through photosynthesis. In this process, chlorophyll captures light energy and uses it to turn carbon dioxide from the air and water from the soil into glucose, a sugar that acts as the plant’s food, while releasing oxygen as a byproduct. The energy stored in glucose fuels the plant’s growth and daily activities. Fermentation is a way some organisms obtain energy without oxygen, not how plants typically produce their food. Respiration uses glucose to release energy but does not describe how the food is made. Transpiration is the movement of water through the plant and its evaporation, not food production.
