A major function of the roots of a plant is to absorb water to produce food for the organism. They need water to produce the glucose product of food, the other reactant is carbon dioxide. This is the process of photosynthesis. The other product is oxygen

- Oxygen, substance all organisms require to survive.

- Glucose, substance produced and used by plant organisms for food.

- Reactant, substances used to make products.

- Carbon Dioxide, gas found floating in air, used by plants to make oxygen.

- Photosynthesis, the process where plants use their chlorophyll to make substances like food
