Which of these is not a type of pigment that can be used for photosynthesis? whoops.
00:08
Carotenoids, chlorophyll b, cellulose, fluorophyll a.
00:12
So photosynthesis involves the capture of light and then using that energy to eventually fix carbon as it's an organic molecule, make sugar.
00:21
So what we need from a pigment is we need a molecule that can capture a photon.
00:33
And importantly, it needs to then be able to pass on that energy.
00:42
Because you don't want the pigment to just keep the energy for itself.
00:45
That energy needs to be used for a purpose, for photosynthesis.
00:49
So it needs to be a molecule that can capture a photon, but hits it, and then pass on the energy from that photon to another useful molecule.
00:56
So which of these cannot do that? well, the answer is cellulose.
01:02
Cellulose is not a pigment...
