1. Photosynthesis & Cellular Respiration

3. Photosynthesis

4. Photosynthesis Vocabulary
Photosynthesis- A process by which plants convert sunlight, water, and carbon dioxide into food energy (glucose), and oxygen.
Chloroplast- organelle containing chlorophyll where photosynthesis takes place.
Chlorophyll- __________________________.

5. Photosynthesis Equation
6 H2O + 6 CO2 + light  6 O2 + C6H12O6
Water+ Carbon + solar  Oxygen + glucose
dioxide energy (carbohydrate)
(Reactants)
(Products)

6. The chlorophyll absorbs the sunlight.
Chlorophyll is the green pigment inside the chloroplasts of plant cells that makes leaves green!

7. Chlorophyll then uses sunlight to change water, carbon dioxide and, nutrients from the soil into glucose and release oxygen.
CO2

8. Cellular Respiration

9. Respiration Vocabulary
Respiration- The process by which the chemical energy of "food" molecules (glucose) is released.
Mitochondria-organelles which convert the energy stored in glucose into ATP for the cell.
ATP- a molecule that is the main energy source for cells (adenosine triphosphate)

10. What do you notice about this equation?
Respiration Equation
6 O2 + C6H12O6  6 H2O + 6 CO2 + ATP
Oxygen + glucose  water + carbon + energy
(sugar) dioxide
(Products)
(Reactants)
What do you notice about this equation?

11. Animals & Plants Rely On Each Other
Animals use: Plants use:
Glucose from plants Carbon dioxide from animals
Oxygen from plants

12. The mitochondria change the O2 and glucose into CO2, H2O, and ATP

13. Cycle of Carbon and Oxygen

14. They are opposites of each other!
Comparing Equations
Photosynthesis Equation:
Water + carbon dioxide + energy  oxygen + glucose
Respiration Equation:
oxygen + glucose  water + carbon dioxide + energy
They are opposites of each other!
