When plants grow where does the material come from?

Plants grow by absorbing water and nutrients from the soil through their roots and carbon dioxide from the air through their leaves. The primary material for their growth comes from photosynthesis, where they convert sunlight, carbon dioxide, and water into glucose and oxygen. This glucose serves as the energy source for the plant, allowing it to grow and develop new tissues. In essence, the bulk of a plant's mass is derived from the carbon dioxide it captures from the atmosphere.
