2. What is Photosynthesis?
The process by which plants and some other organisms capture and use light energy to make food from carbon dioxide (CO2) and water (H2O)
photosynthesis is a chemical reaction.
It is ONE of the most important
chemical reaction on our planet.

3. the equation for the chemical reaction of photosynthesis?
CO2 + H C6 H12 O2 + O2
Photosynthesis clip

4. CO2 + H20 C6H1206 + 02 6CO2 + 6H20 C6H1206 + 602 A Balanced Equation
Six molecules of carbon dioxide react with six molecules of water to form 1 molecule of glucose and six molecules of oxygen.

5. Describe Photosynthesis
The process of changing light energy to chemical energy
Energy stored as sugar
Occurs in plants and some other autotrophs like algae
Plants need light energy, CO2, and H2O
Takes place in the chloroplasts, using chlorophyll, the green pigment in plants

6. What happens during photosynthesis?

7. What happens during photosynthesis?
Plants capture light energy and use that energy to make glucose
Sunlight provides the energy needed by chlorophyll to change molecules of carbon dioxide and water into glucose
Oxygen is also released in this reaction

8. What happens during photosynthesis?
Carbon dioxide enters the leaf through holes called stomata
CO2 combines with the stored energy in the chloroplasts through a chemical reaction to make glucose
The sugar is moved through tubes in the leaf to the roots, stems and fruits of the plants
Some of the sugar is used right away by the plant for energy; some is stored as starch; and some is built into plant tissue

9. Why is this important to us?

10. Why is Photosynthesis important?
We cannot make our own food (glucose, energy), we must get our food from plants.
Plants are the first step in the food chain.
The oxygen released during photosynthesis is necessary for all living things.
