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
Bundle Sheath Cells
They are tightly packed sheaths around the veins of the leaf
They release CO2 for the Calvin cycle to use
What is the acronym for wavelengths
Raging martians invaded Venus using xray guns
What are C3 plants
Bundle sheath cells that are not photosynthetic
Most photosynthesis happens in mesophyll
C4 plants
Takes in CO2 and turn it into 4 carbon compounds that are transferred to mesophyll cells
Ex) happens in cacti to conserve water
What happens to electrons when wavelength are absorbed
Electrons are energized
Photons excite
Photosynthetic electrons
What color of light do plants use most for photosynthesis
Red
Thylakoids is made up of
Chlorophyll a
Chlorophyll b
Carotenoids
Mesophyll cells are made of
Chloroplasts
