Final answer:
Plants use the sun's energy to manufacture sugar through photosynthesis. Glucose, the sugar produced, serves as energy and building blocks for the plant.
Step-by-step explanation:
Plants use the sun's energy to manufacture sugar through a process called photosynthesis.
During photosynthesis, plants take in carbon dioxide from the air, water from the soil, and sunlight as an energy source. These three components combine to produce glucose, a type of sugar, as well as oxygen as a byproduct.
The glucose produced during photosynthesis serves as a source of energy and building blocks for the plant. It is used to fuel metabolic processes, such as growth and reproduction, and to synthesize other important molecules like proteins and carbohydrates.
