Most common agricultural plants are...
C3
Which plants are considered drought resistant?
C4
What by-product of cellular respiraiton is required for photosynthesis?
Carbon dioxide
The chemical reactions of photosynthesis occur in which cellular organelle?
Chloroplasts
We use energy in many ways. What is one thing we cannot do to energy?
Destroy it
In photosynthesis the plant produces its food...
During the light-independent phase
Identify the stage of cellular respiration where glucose is split into two molecules of pyruvic acid?
Glycolysis
How do we know green light is not absorbed by chlorophyll?
Green light is the wavelength of light that is reflected instead of absorbed by the chloroplasts.
What is the role of light in photosynthesis?
It excites/energizes electrons
Identify the role of carbon dioxide in photosynthesis.
It is split to become incorporated into sugars
Can cell respiration proceed without glucose?
No answer text provided
Alcohol is a waste product produced by yeast in the presence of sugar and the absence of ________.
O2
Why do some leaves change color (red, yellow, orange, etc.) in the fall?
The chlorophyll molecule breaks down and other pigments now become visible.
What molecules link the light reactions and the Calvin cycle?
The electron shuttles
Yeast is used to produce beer and wine but can also make bread rise. All of these processes involve the production of alcohol. Explain why you can eat bread and not get drunk.
The heat of cooking bakes out the alcohol
Where do the molecules used as the inputs of the Calvin cycle come from?
They come from the light reactions
Which of the following best describes the chemical equation for photosynthesis?
Water + Carbon dioxide + Energy = Sugar + Oxgen
What is aerobic fermentation?

both
Which processes can be carried out by producers?
both photosynthesis and cellular respiration
Which stage of cellular respiration requires oxygen that you breathe?
