photosynthesis in artificial light

04/02/2009 4:32 AM

We all know that trees absorb carbon dioxide when the sunlight is there. The sun light constitutes 7 visible colors and then we have infrared and ultraviolet. Which of these 9 colors aids photosynthsis /absorption of carbondioxide?

Sounds like a homework question to me. Is it?

Look at the color of the leaf and then check which color of the spectrum it absorbs best. I'll do the first one for you: Green leaf = red light. If you want to know what color light the different colored seaweeds absorb best, you'll have to find out for yourself.

Dear mr answers to Emperor Palpatine:

I KNOW that you know that.

I saw know indication of the science behind this fact in the way he worded the question, which is why i posted the Hint.

Trying to actually inject a little science.

I try to avoid using their wrong terms ever ssince I got marked down in a plant physiology class for calling "sporangia" on the back of ferns "Copules."

Professor thought that a college boy ought to use the real name., not the ones the family had been using for generations...

Thanks for the comeback, criticism of your post was NOT my intention.

NOW PUT THAT LIGHT SABER DOWN!

That probably explains the substitution of many of your extremities with mechatronix...

Yeah, I never could figure out Yoda's trick in using the Force to deflect energy fields like a lightsaber blade .

Different shades of green in plants are tailored to the light sources in their environment. Moss, for example, has pigments that absorb enough energy in the shady forest where it is adapted to live. Plant chemistry adapts to strong light conditions too.

Google for chlorophyll or "Photosynthetic pigments".
