photosynthesis

[rowina]

I found the following information on answerbag, however, because it was on this website, I need someone with an actual qualification to back it up. Also, is it correct?

"Actually, chlorophyll a has two peaks of best efficiency, one in the blue part of the spectrum (around 430 nm) and one in the red part of the spectrum (680 nm); however, there are "associated pigments" which take advantage of almost every part of the visible spectrum, and most of the energy absorbed is passed along a line of receptors (losing bits along the way, of course) until the energy is equivalent to that absorbed at 700 nm. Photosynthesis is *least* effective in the green-yellow part of the spectrum, around 520-550 nm."

Hi,

I believe this is what you are looking for? A reference that is better than answer bag? I don't have any direct plant experience, but can help you find better references to work with.
