Question 1

Photosynthesis

Answer 1

Energy for almost all life on earth
6CO2 + 12H2O + light ->C6H12O6 +6H2O + 6O2

Question 2

Photosynthesis in plants

Answer 2

Occurs in chloroplasts

Question 3

Light dependent reactions

Answer 3

-require light
-occur in the thylakoid
-capture energy from sunlight
-make ATP and reduce NADP to NADH
-produce O2 as a byproduct

Question 4

Light independent reactions

Answer 4

-does not require light
-occur in the storma
-use ATP and NADPH to synthesize organic molecules from CO2

Question 5

Pigments

Answer 5

Molecules that absorb photons of visible light

Question 6

Photons

Answer 6

Particle of light that acts as discrete bundle of energy

Question 7
