Question

What do plants use for energy?
Glucose
Oxygen
Water
Fructose

Answer 1

Plants primarily use glucose as their main source of energy. They produce this glucose through the process of photosynthesis, where they convert sunlight, water, and carbon dioxide into glucose and oxygen. Oxygen produced during photosynthesis is released into the atmosphere, while glucose is used by the plant for energy and other metabolic processes. Fructose can also be produced by plants and used as an energy source, but glucose is more commonly utilized. Water is essential for photosynthesis, but it is not directly used by plants as a source of energy.
