3. Photosynthesis Notes

4. Describe Photosynthesis
The process of changing light energy to chemical energy which is stored as sugar
Occurs in plants and some algae
Plants need sunlight, Carbon Dioxide (CO2 ), and Water (H2O) as REACTANTS
Describe Photosynthesis

5. Occurs in the ____________of plants
___________is the green pigment inside chloroplasts that absorb sunlight
chloroplasts
Chlorophyll

6. As the chlorophyll in leaves decays in the autumn, the green color fades and is replaced by the oranges and reds of carotenoids.

CO₂ O₂
H₂O
Glucose
CHLOROPLASTS. Performs photosynthesis. It will take water and carbon dioxide, and change it in to oxygen & glucose… it’s a very simple process.

9. The Photosynthesis Song

10. Photosynthesis:
Photosynthesis is the process by which the energy of sunlight is converted into the energy of glucose.
carbon dioxide  +  water  +  light                         glucose  +  oxygen
6CO H2O + light C6H12O O2

11. Photosynthesis:
Photosynthesis is the process by which the energy of sunlight is converted into the energy of glucose.
carbon dioxide + water + light glucose + oxygen
REACTANTS PRODUCTS

12. Photosynthesis:
Photosynthesis is the process by which the energy of _________ is ________ into the energy of __________
carbon dioxide + water + light glucose + oxygen
______________ ______________

13. What happens during photosynthesis?
Sunlight provides the energy needed to change carbon dioxide and water into glucose
Oxygen is released as a waste
What happens during photosynthesis?

14. 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

15. Why is this important to us?
Without photosynthesis, plants wouldn’t exist.
We cannot make our own food (glucose, energy), we must get our food from plants.
The oxygen released is necessary for
ALL living things.
Remember: Producers/Plants are the base of the food chain!
Why is this important to us?

16. Water, Sunlight, Carbon Dioxide
