1. Photosynthesis or How Plants Make Food

2. Energy from the Sun is necessary to begin the process. Besides green plants, some algae and some bacteria can also make their own food.

3. Radiant energy from the Sun, in the form of light, begins photosynthesis. Chlorophyll must also be present

4. Water is taken into the plant by the roots and carried to the leaves through the xylem. H20H20 H20H20 H20H20 Xylem is a series of tubes.

5. Carbon dioxide gas (CO 2 ) is taken into the plant through the stomata on the underside of leaves. H20H20 H20H20 H20H20 CO 2

6. H20H20 H20H20 H20H20 O2O2 O2O2 O2O2 One product of photosynthesis is Oxygen gas (O 2 ) that is released into the atmosphere through the stomata on the underside of leaves.

7. H20H20 H20H20 H20H20 Sug The other product is glucose that the plant uses for food.

8. Sugar The other product is glucose that the plant uses for food. That animals can eat! Sugar

9. H20H20H20H20H20H20 CO 2 O2O2 O2O2 O2O2 Sugar Review the process. Explain each step as it is shown. Sugar

10. H20H20H20H20H20H20 CO 2 O2O2 O2O2 O2O2 Sugar Remember, this process is continuous in light.. Sugar

11. The formula for photosynthesis is

12. Photosynthesis is important to all life on Earth. Plants and plant-like organisms replace oxygen used by animals when they breathe and us the carbon dioxide the animals exhale. The light energy from the Sun is converted into matter through a chemical reaction. The glucose produced is used both to keep the plants alive and stored to be used by animals that eat the plants. The animals convert the plant matter to chemical energy when the plants are digested and used a fuel by the animal.
