Pigments

... Red are the major parts of the spectrum where chlorophyll absorbs light. This doesn't mean that green light isn't used at all, especially by other pigments such as carotenoids. I would expect that they wouldn't grow as fast, and that perhaps the leaves will produce less chlorophyll (less green).

... wavelengths of light, then measuring growth (change in numbers). Also, I was wondering if it would be interesting for him to try to detect pigments in the algae using a chromatogram. I have found some resources on this, but I was wondering if paper chromatography would work and if some ...

... blue and violet light that has the most at 400 nm wavelenght, followed by green which I think is 500. Also I think, if I remember right, that some pigments do utilize the green wavelength.

it also depends on what "red pigments" you are considering. The red pigment mkwaje was referring to is phycoerythrin, which indeed has the role to allow the organism to use light that would otherwise be useless. However, most land ...

I agree with that herb86, many photosynthetic plants /algae found some distance below the surface contain red pigments so that they can utilize the red wavelength, which is basically almost the only light wavelength that can reach deeper waters. Another thing, many scientists ...
