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. Oxygen gas (O 2 ) is released into the atmosphere through the stomata on the under side of leaves. H20H20 H20H20 H20H20 O2O2 O2O2 O2O2

7. Water vapor is released into the atmosphere through the stomata on the leaves. H20H20 H20H20 H20H20 This process is called transpiration.

8. H20H20H20H20H20H20 CO 2 O2O2 O2O2 O2O2 H20H20 H20H20 H20H20 Review the process. Explain each step as it is shown.

9. H20H20H20H20H20H20 CO 2 O2O2 O2O2 O2O2 H20H20 H20H20 H20H20 Remember, this process is continuous in light.
