Explanation:

1. Plants absorb sunlight, water (from roots), and carbon dioxide (from air).
2. Chlorophyll in chloroplasts captures light energy.
3. Light energy splits water into oxygen (released) and hydrogen.
4. Hydrogen combines with carbon dioxide in the Calvin cycle.
5. This produces glucose (stored as starch, used for energy), with oxygen as a by - product.

Answer:

1. Plants take in sunlight, water, and carbon dioxide.
2. Chlorophyll captures light energy to split water into oxygen and hydrogen.
3. The hydrogen and carbon dioxide enter the Calvin cycle.
4. The Calvin cycle produces glucose (and oxygen is released).
5. Glucose is used or stored (e.g., as starch).
