What elements are rearranged to make glucose in plants?

In plants, glucose is synthesized primarily through the process of photosynthesis, where carbon dioxide (CO₂) from the atmosphere and water (H₂O) absorbed by the roots are rearranged. Chlorophyll in the chloroplasts captures sunlight, which provides the energy needed to convert these reactants into glucose (C₆H₁₂O₆) and oxygen (O₂) as a byproduct. The overall process involves the transformation of carbon, hydrogen, and oxygen atoms into a stable sugar molecule.
