Question 1

thylakoid function in photosynthesis

Answer 1

contains light harvesting pigments, e- transport chain

Question 2

stroma function in photosynthesis

Answer 2

contains enzymes for calvin cycle (rubisco)

Question 3

thylakoid lumen function in photosynthesis

Answer 3

moving H+ in forms proton gradient
H+ out forms ATP by ATP synthase

Question 4

reactants and products of respiration

Answer 4

reactants: sugar and O2
products: CO2 and H2O

Question 5

reactants and products of photosynthesis

Answer 5

reactants: CO2 and H2O
products: sugars and O2

Question 6

coleus leaf experiment findings

Answer 6

starch production in areas with green pigment (chlorophyll)
chlorophyll present in chloroplasts, absorbs light energy for photosynthesis

Question 7

what colors/wavelengths does chlorophyll a absorb?

Answer 7

red (approx 600 nm) and blue (approx 400 nm)

Question 8

TLC experiment findings

Answer 8

most hydrophobic pigments travel farthest

Question 9

accessory pigments function

Answer 9

collect light energy, transfer chlorophyll a at reaction center

Question 10

green seedlings TLC colors

Answer 10

orange, green, and yellow pigments
chlorophyll a and b

Question 11

yellow seedlings TLC colors

Answer 11

yellow, sometimes orange pigments
