4. Photosynthesis & Respiration
L.O. Students will be able to describe the process of photosynthesis and cellular respiration.

5. What is Photosynthesis
What is Photosynthesis? photo: light synthesis: putting together The process of photosynthesis is a chemical reaction. It is the most important chemical reaction on our planet.

6. Describe Photosynthesis

7. What is the equation for the chemical reaction of photosynthesis?
Six molecules of carbon dioxide react with six molecules of water to form 1 molecule of glucose and six molecules of oxygen.

8. Describe Photosynthesis
process changing light energy to chemical energy.
Need: light energy, CO2, and H2O
Energy stored as sugar, Oxygen is released
Occurs in plants and some algae
Takes place in the chloroplasts, using chlorophyll, the green pigment in plants

9. What happens during photosynthesis?
Carbon dioxide enters the leaf through holes called stomata.
Stoma
Mesophyll
Cell
Chloroplast

10. Chloroplast Organelle where photosynthesis takes place. Stroma
Outer Membrane
Thylakoid
Granum
Inner Membrane

11. What happens during photosynthesis?
Draw this in your notebook

12. Why is photosynthesis important to us?

13. Why is photosynthesis important to us?
Plants are the first step in the food chain.
We cannot make our own food (glucose)
We must get our food from plants
oxygen released during photosynthesis is necessary for all living things.

14. What is Cellular Respiration?
The release of chemical energy for use by cells.

15. What is Cellular Respiration?
Once the energy that was in sunlight is changed into chemical energy by photosynthesis, an organism has to transform the chemical energy into a form that can be used.
This process is cellular respiration.

16. Describe Cellular Respiration
The breakdown of glucose molecules to release energy
Takes place in all living things
step by step process

17. What is the chemical equation for cellular respiration?

18. What is the chemical equation for cellular respiration?

19. How are photosynthesis and cellular respiration related?
The equations.... What one produces the other releases.

20. Photosynthesis
6O₂ + CH₁₂O₆ CO₂ + 6H₂O
Respiration
