Answer 10

carbon fixation

Question 11

What does the cuticle do?

Answer 11

chloroplast

Question 15

What is the inner fluid of the chloroplast called?

Answer 15

stroma

Question 16

What are thylakoids filled with?

Answer 16

chlorophyll (green pigments)

Question 17

What is the equation for photosynthesis?

Answer 17

6CO2 + 6H2O + energy –> C6H12O6 + 6O2

Question 18

Where do light-dependent reactions occur?

Answer 18

membranes of thylakoids

Question 19

What happens in light-dependent reactions?

Answer 19

chlorophyll absorb sunlight, electrons gain energy and can pass down the electron transport chain, given to NADP+, forming molecule of NADPH
molecule of water= split into hydrogen and oxygen
Oxygen is released as a waste product and hydrogen is used to make ATP
