1. HW: Flashcards due Thursday Do Now: Think of the plants near your house, flowers in a garden, or trees outside the school. What do they need to stay alive? What causes them to die? --

2. Aim: What is Photosynthesis?
Do Now: Why Do Cells Need Energy?
2. What is the name of the energy molecule?
3. Where is energy Stored in a molecule of ATP?
4. How is energy stored and release from ATP?

3. What happens in photosynthesis?
Light
“synthesis”
Making compounds
It uses light from the sun to make a compound (glucose)

4. Types of Nutrition Autotrophs -
Plants and some protists that are able to make their own food

5. How do autotrophs make food?
Photosynthesis –
Uses energy in the form of light to make food
The food made is glucose
Sunlight
Oxygen
Carbon Dioxide
Water

6. Heterotrophs Heterotrophs can NOT directly use the sun’s energy
Examples: Animals, Humans
Animals have to
EAT plants and/meat
to get energy

7. Photosynthesis Materials (what is needed) Water CO2 Sunlight Products
(what is made)
Glucose
Oxygen
Water

8. Photosynthesis Equation:
Carbon Dioxide + Water + Energy (Sun light)
Food (glucose), Oxygen, and water

9. Chemical Equation: CO2 + H2O  C6H12O6 + O2 + H2O Summary:
Carbon Dioxide
Water
Glucose
(simple sugar)
Water
Oxygen
Summary:
Inorganic Compounds  Organic Compound I

10. Photosynthesis
Photosynthesis song

11. Where does Photosynthesis take place?
Chloroplasts-
Organelle where photosynthesis takes place.

12. Chloroplast in Moss

13. Inside A Chloroplast Chlorophyll- Chlorophyll is why plants look green
Green pigment that captures light from the sun
Chlorophyll is why plants look green

14. Solar Energy
The sun is needed for photosynthesis because of its energy!

15. Light is made up of many different colors !
Chlorophyll captures RED & BLUE
light to use for photosynthesis
Plants reflect GREEN light

16. Light Energy Chemical Energy
Summary of Photosynthesis
Light Energy Chemical Energy
(Sun)
(Glucose)

17. Lets Review…
1. What is a heterotroph? 2. What is an autotroph? 3. Give a simple definition of photosynthesis. 4. Name the materials needed for Photosynthesis. 5. In what organelle does photosynthesis take place? 6. What is the name of the green pigment found in plants?
Can’t make its own food. Has to eat to get nutrients.
Makes its own food EX: Photosynthesis in plants.
Using light energy to make food (organic compounds)
Light Energy (SUN), Water, Carbon Dioxide
Chloroplast
Chlorophyll

18. Why is this funny!?! (Yes, it’s funny)
Why is photosynthesis important for plants?
Why is it important for us????

19.
Discovery of Photosynthesis
