10.2 sunlight

Question 1

pigments

Answer 1

absrob light

Question 2

spectrophotometer

Answer 2

measure wavelength of light

Question 3

pigment’s absorption spcetrum

Answer 3

a pigment;s light absoption vs. wavelength

Question 4

action spectrum

Answer 4

shows that green is the worst for photosynthesis

Question 5

carotenoids

Answer 5

photo protection: they absorb light that would damage chlorophyll or interact with oxygen

Question 6

what happens when light is absorbed

Answer 6

and electron is boosted to an orbital of higher energy
-having more potential energy
“excited” state

Question 7

what happens after the excited state usually

Answer 7

the electron drops back to its old orbital, releasing heat

Question 8

fluorescence

Answer 8

when chlorophyll gives of photon light after falling back to ground state

Question 9

photosystem

Answer 9

a reaction center complex surrounded by several light harvesting complexes
(thykaloid membrane)

Question 10

reaction center complex

Answer 10

2 chlorophyll a and a primary election acceptor

Question 11

what happens when photon enters a photosystem,

Answer 11

the energy is transferred from pigment to pigment until it gets to the chlorophyll a

that transfers it to the primary electron acceptor

Question 12

2 types of photosystems in thykaloid membrane

Answer 12

photosystem II and photosystem I

in order of function

Question 13

chlorophyll a of photosystem II

Answer 13

p680

-best at absorbing light with 680 wavelength (red)

Question 14

chlorophyll of photosystem I

Answer 14

P700

far red
