b) When the water molecules present in the cells are split by the energy from the sunlight
c) Oxygen isn't a product of photosynthesis, it's a reactant
d) It's made by ATP synthase, an enzyme specific to the production of oxygen

Where does the light dependent reaction take place in the chloroplast?

b) Solar to chemical
c) Mechanical to nuclear
d) Chemical to mechanical

What role does NADPH play in the process of photosynthesis?
a) It is an energy molecule, delivering energy from the light dependent reaction to the light independent reaction.
b) It does not play a role in photosynthesis.
c) It is an electron taxi, delivering electrons from the light dependent reaction to the light independent reaction
d) It's the polymer molecule that plants store excess glucose as

The enzyme that makes ATP during the light dependent reaction is called...
a) ATP synthase
b) ATP synthose
c) ATP productase
d) ATP productose

The light independent reaction is also known as..
a) The Coolidge Cycle
b) The Creeper Cycle
c) The Hobbes Cycle
d) The Calvin Cycle

What starts the Calvin Cycle?
a) Water
b) Sunlight
c) Carbon dioxide
d) Glucose

Where does the Calvin Cycle occur?
a) In the thylakoid membrane
b) In the stroma
c) In the stomata
d) In the mitochondria

What is the main pigment inside the chloroplast that absorbs the light energy to start the process of photosynthesis?
a) Chlorophyll
b) Carotenoids
c) Xanthophyll
d) Beta-carotene

Why are plants green?
a) All the chlorophyll pigments inside the plants are green, so the plants appear green.
b) The chlorophyll pigments absorb all other wavelengths of light except green.
c) Carotenoids reflect the green wavelength
d) Xanthophylls reflect the green wavelength

Plants use the energy of the sun to make food. What is their food molecule?
a) Sucrose
b) Lactose
c) Fructose
d) Glucose

a) Heterotrophs
b) Autotrophs
c) Evil
d) Smart

The correct equation for photosynthesis is...
