What does the word “producer” mean?Describe what comes to mind when you
hear the word producer.Give some examples of producers.
Objectives:
Relate producers to photosynthesisDescribe the process of photosynthesis
Photosynthesis:a process that captures energy from
the sunlight to make sugars that store chemical energy
Miss HannaBiology I
1) Formula
6CO2 + 6H2O + Energy (Sunlight)6O2 +C6H12O6
Carbon dioxide + Water + Energy Oxygen + Glucose
2) Purpose
To capture energy ◦Sunlight ATP
Make glucose (sugar)
3) Location
Plants onlyOrganelle: ChloroplastStructures Inside a
Chloroplast (write under notes)◦ Thylakoids: saclike
photosynthetic membranes in chloroplast
◦ Grana (granum): stacks of thylakoids
◦ Stroma- region outside thylakoid membrane
Chlorophyll: a molecule that absorbs some of the energy in visible light DRAW &
LABEL THIS!
4) Cycles of Photosynthesis
2 Cycles in Photosynthesis◦4a) Light Dependent Reaction
Produces ATP◦4b) Light Independent -Calvin Cycle
Uses ATP from Light Reaction Creates Sugar from Carbon dioxide
4a) Light-Dependent Reactions
Location: Takes place in grana/thylakoidReactants: H20 and energy from light Products: oxygen gas Goal: convert ADP and NADP into the
energy carriers ATP and NADPH (carries electrons for energy) for light independent reactions
4b) Light-Independent Reactions “Calvin Cycle”
No light requiredLocation: StromaReactants:
◦ATP and NADPH created in the light dependent reactions
◦Uses CO2Products: high energy sugars (glucose
Light vs. Calvin
Draw this picture in your notebook
Calvin Cycle
5) Factors Affecting Photosynthesis
Amount of water in the environment◦ shortage can slow/stop photosynthesis
5) Factors Affecting Photosynthesis
Temperature◦Between 0-35C degrees is ideal
5) Factors Affecting Photosynthesis
Light intensity◦Increase light will increase in photosynthesis
until max rate is reached
