1. PHOTOSYNTHESIS Solar Energy to Chemical Energy
EQ: Can I name the inputs and outputs of photosynthesis and identify where in the leaf photosynthesis occurs?

2. Producers
Plants are called producers because they produce or make their own food from sunlight through the process of photosynthesis (“building from light”)

3. Process of photosynthesis
sun
Takes water and carbon dioxide +
The energy of sunlight
To produce
Glucose (sugars)
Sugars are then used for:
Energy for life processes
To build the structures in the plant +
H2O
CO2
sugars

4. Chemical Formula for Photosynthesis
 glucose + oxygen
carbon
dioxide
sun
energy
+ water +
6CO2
6H2O
C6H12O6
6O2
sun
energy  +
What are the reactants?
What are the products?

5. Where does photosynthesis happen?
What do plants need to grow?
Fuels
sunlight
carbon dioxide
water
The Helpers
enzymes
The chloroplast:
Make ATP! Make sugar! I can do it all… And no one even notices!
sun
CO2
ATP
sugars
enzymes
H2O

6. Chloroplasts are only in plants
animal cells
plant cells

7. Chloroplasts
Chloroplasts are in the palisade layer of the leaf (top of the leaf)
Contain chlorophyll, which absorbs the sunlight’s energy
Chlorophyll absorbs all colors of light except green, which it reflects
sun
CO2
Chloroplast
make ENERGY & SUGAR

8. Use your manipulatives…
Light
NADP+
ADP + P
Light-
Dependent
Reactions
Calvin
Cycle
ATP
NADPH O2

9. So what does a plant need?
Bring In
light
CO2
H2O
Let Out O2
Move Around
sugars
6CO2
6H2O
C6H12O6
6O2
light
energy  +

10. The poetic perspective
All of the solid material of every plant was built out of thin air
All of the solid material of every animal was built from plant material
sun
air
Then all the cats, dogs, mice, people & elephants… are really strands of air woven together by sunlight!
