Photosynthesis Chapter 8
What do all living things need? ENERGY
Energy All cells use energy to perform cellular processes The energy is called ATP P
Energy P Energy is stored in the bonds of compounds Then how is energy released by ATP? P P
P P P ATP Energy Released P ADP P + P
What do we do to get energy? We eat food! All living things need food to survive!
How do living things get food? Heterotrophs – consume food by eating other living things Autotrophs – organisms that make their own food How do plants make their own food?
Photosynthesis The process by which plants use energy from the sun to produce high energy carbohydrates, such as sugar and starches
What is the equation for Photosynthesis? 6 CO 2 + 6 H 2 O C 6 H 12 O 6 + 6 O 2
Where does photosynthesis happen? In the chloroplast, a unique organelle of plant cells
Photosynthesis Photosynthetic organisms capture energy from the sunlight with pigments Chlorophyll This is why plants are green!
What is the equation for Photosynthesis? 6 CO 2 + 6 H 2 O C 6 H 12 O 6 + 6 O 2
Photosynthesis has many steps The equation just sums up what goes in and what comes out
sun H 2 O ENERGY building reactions ATP ADP SUGAR building reactions used immediately to synthesize sugars sugar CO 2

What affects Photosynthesis?
In Your Lab Notebooks… Create a Data Table showing what variables you’re manipulating, and the results of the variable. Create a graph showing the results of the simulation. Answer the questions on the next slide.
Answer these questions… 1. What is your control in each simulated experiment? 2. How did your variables affect photosynthesis? Why? 3. Explain how you think another variable that you are unable to test in this simulation would affect photosynthesis. Why? Explain in full sentences!
