1. Photosynthesis foldable activity
Don’t fold anything yet!

2. The Photosynthesis Equation
Write your name and period at the bottom on the lines provided. Next to this, we are going to write the photosynthesis equation.
To start the equation, think about what the plant takes in from the environment...
6CO2 + 6H2O light

3. Now, what are the products?
Think about what heterotrophs must take in to survive…
high-energy
Glucose

4. Now fold the top of your paper down so that the equation still shows, but you can see Photo-synthesis on the top.
What does PHOTO mean?
LIGHT

5. WHOooo? WHO does photosynthesis?
In the pentagon: what do we call organisms that make their own food?
3 Arrows from AUTOTROPHS:
We all know plants undergo photosynthesis, but what else?
some bacteria
algae

6. Sequence of events: Light absorption Light Dependent Reactions
Electron Transport Chain
Chemiosmosis
Calvin Cycle

7. Inside a Chloroplast Thylakoid Grana Chlorophyll/pigments Photosystems
Stroma

8. Light-Dependent Reactions
Where do they take place?
Thylakoid membranes of chloroplasts
What goes in (USES)?
H20
ADP
NADP+
What comes out (PRODUCES)? O2
ATP
NADPH

9. The Calvin Cycle (Light-Independent Reactions)
Where do they take place?
Stroma of chloroplasts
What goes in (USES)?
ATP
NADPH
CO2
What comes out (PRODUCES)?
Glucose
ADP
NADP+

10. Electron Carrier What does that mean?
In photosynthesis, the electron carrier is:
NADP+
accepts electrons with the H+ and becomes NADPH
Happens in e- transport chain (chemiosmosis)

11. Inside a Chloroplast H2O CO2 Light NADP+ ADP + P
Light- dependent reactions
Calvin Cycle

The process of photosynthesis includes the light-dependent reactions as well as the Calvin cycle.

12. Factors affecting photosynthesis
1: Temperature
The reactions of photosynthesis are made possible by enzymes that function best between 0°C and 35°C.

13. Factors affecting photosynthesis
2: Light
High light intensity increases the rate of photosynthesis. After the light intensity reaches a certain level, however, the plant reaches its maximum rate of photosynthesis

14. Factors affecting photosynthesis
3. Water
Because water is one of the raw materials in photosynthesis, a shortage of water can slow or even stop photosynthesis.
What special adaptations do plants that live in dry climates have?

15. close it and flip it over
On the back side of PHOTOsynthesis, draw the ATP molecule.
adenosine triphosphate (ATP).
ATP consists of adenine, a 5-carbon sugar called ribose, and three phosphate groups.
How is the energy released?
What is ADP?
