Chapter 10 Flashcards
The biosphere is fed by
Photosynthesis
Plants are
Photoautotrophs
Photoautotrophs
Use light energy To make its own food
Where does photosynthesis occurs
In chloroplasts
What makes up chloroplast
Grana of Thylakoids 
What are the function of thylakoids 
They are the individual sacks in chloroplasts that split water to release oxygen which produces ATP and forms NADPH
The function of chloroplasts
Splits hydrogen and oxygen
Puts hydrogen into sugar molecules
Where does the Calvin cycle happen
In the stroma
What does the Calvin cycle do
Forms sugar from CO2
Uses ATP for energy and NAPH for reducing power
Function of chlorophyll
Absorbs light specific wave lengths
What happens when a photon boost a pigment to a higher energy level
The photon goes from a ground state to an excited state
Excited states stable or unstable
Unstable
How is heat or light given off
What electrons from isolated pigments fall back to ground state
Photo stem process
Look at notes
What happens when the stomata closes
Photorespiration occurs
Meaning that C02 is released and decreases the photosynthetic input
