Light is necessary for proper plant growth because

• A. It is necessary for manufacturing of carbohydrates (food)
• B. Keeps plants warm
• C. Is it necessary for plants to breath
• D. It is necessary for the plant to produce flowers

Answer: (A)

Light provides the energy that plants use to power photosynthesis, the process that turns carbon dioxide and water into glucose, a carbohydrate. This carbohydrate fuel is what plants rely on for energy and as the building blocks to form cell walls and grow. Without light, photosynthesis cannot run, so the plant cannot manufacture carbohydrates and growth slows or stops. While light can contribute to warmth, and plants do respiration using sugars, these facts don’t explain why light is essential for growth in the way photosynthesis does. Flower production can be influenced by light in some species, but it isn’t the universal reason plants need light. So, the core reason is that light drives the production of carbohydrates that fuel growth.
