Benchmark #3 Flashcards
Where does the light independent reaction occur?
The stroma
Plants appear to be green because…
Chlorophyll reflects green light
What at three factors that affect photosynthesis?
Water
Light intensity
Temperature
Autotroph or heterotroph?
-humans
Heterotroph
True or false…
A plant exposed to only green light will grow better the. With white light.
False
Where is the chlorophyll located in a chloroplast?
In the thylakoids.
Where does the oxygen come from in the light dependent reaction?
Released when water is split
What substances is produced by photosynthesis to be used as food for the plants?
Glucose
An organism that can create it’s own food is called a(n)….
Autotoph
An organism that needs to consume other organisms to gain energy is called a(n)…
Heterotroph
Why do black surfaces get hotter than white surfaces in sunlight?
Black absorbs all light energy, white reflects all light energy
What do we call a light absorbing chemicals

Starch
Where in the chloroplast does the light dependent reaction occur
In the thylakoids
What are two other names for the light independent reaction?
Calvin cycle
Dark reaction
Which contains more stored energy, ATP or AMP
ATP
How is energy released form the ATP molecule?
By removing a phosphate to make ADP
Why is done to store energy on a molecules of ADP
A phosphate group is added to form ATP
Is ATP Useful for long-term energy storage?
No, only for a short time
What are the tree parts if ATP molecule?
Phosphate

What is the job of NADPH
It’s an electron carrier
What are a stack of thylakoids called?
Grana or granum
