Photosynthesis Pre Assessment

Why does chlorophyll look green to the human eye?

• Chlorophyll absorbs green light.
• Chlorophyll is green as the result of an optical illusion created by light transmission.
• Chlorophyll absorbs blue and yellow light, which make green.
• Chlorophyll reflects green light.

C​₄​​ plants are able to drastically reduce photorespiration compared to C​₃​​ plants.

• C​₄ plants do not undergo the Calvin cycle.
• C​₄​​ plants use PEP-carboxylase for initial CO₂ fixation.
• C​_4​​ plants have stomata that are open only at night.
• C​₄​​ plants are adapted to cold wet environments.

In the diagram, which represent the reactants that are needed for the Calvin Cycle to produce G3P?

• CO₂
• NADPH
• ATP
• All are needed 

Photosynthesis can be divided into two steps: the light-dependent reactions and the Calvin cycle.
Which of the following is true regarding these two steps?

• The light-dependent reactions take place in the thylakoid membrane, and the Calvin cycle takes place in the stroma.
• The Calvin cycle converts water molecules into oxygen gas as a byproduct of its reactions.
• During the light-dependent reactions, carbon dioxide is fixed to produce sugars that form glucose.
• The light-dependent reactions use ATP from the Calvin cycle, and the Calvin cycle uses energy from absorbed sunlight.
