lab report on photosynthesis?

Question

i have to do a "background of subject under study" on my lab report, and my lab was different wavelengths (colors) and its affect on photosynthesis. what would i say about the background (i am terrible at biology)? Would I just say

"Higher wavelenghts of light are absorbed, which increase the action of photons. The higher the wavelength, the more light is absorbed, which increases the rate of photosynthesis as compared to lower wavelengths."

Answer 1

Why were you doing the experiment? Do you have any reason to suspect that photosynthesis may operate differently at different wavelengths? For example, when you look at a photosynthesizing structure (like a leaf), do you see a particular color? Consider that the color you see is a visual representation of the light which is _not_ absorbed to power the photosynthesis reaction. It may not be simply the higher the wavelength - perhaps specific colors (wavelength ranges) have different affects on photosynthesis activity?

Answer 2

From what I know, chlorophyll (the most common pigment in plants) absorbs light maximum at red and blue lights (about 700 and 400 nm in wavelength) and the minimum at the green light.

Theoretically, rate of photosynthesis should be the greatest in red and blue lights.
