1. Photosynthesis & Respiration

2. What is Photosynthesis?
The process of photosynthesis is a chemical reaction.
Photosynthesis is a process that occurs in plants to turn simple, inorganic molecules (H2O, CO2 ) into complex food molecules
(C6H12O6) like glucose

3. Write the Equation for the Chemical Reaction of Photosynthesis in WORDS.

4. carbon dioxide reacts with water to form glucose and oxygen.

5. What is the equation for the chemical reaction of photosynthesis?

6. Describe Photosynthesis at least four (4) things!

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

8. What happens during photosynthesis?

9. 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

10. Why is this important to us?

11. Why is this important to us?
We cannot make our own food (glucose, energy), we get our food from plants.
Plants are the first step in the food chain.
Also, plants release OXYGEN for aerobic respiration

13. What is Cellular Respiration?

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

15. What is Cellular Respiration?
Process that breaks down glucose in the mitochondria to release energy in the form of ATP
This process occurs in the mitochondria
It happens in all living things

16. Describe Cellular Respiration

17. Describe Cellular Respiration
The breakdown of glucose molecules to release energy
Takes place in all living things
Takes place in the mitochondria
Opposite (reverse) of photosynthesis
