Today in Mr. Wong's bio class, I learned about the color of light affecting photosynthesis. You can read about it more in the post above this one (titled Photosynthesis Lab). Anyway, to see how one variable can change an outcome greatly, I did an experiment twice but only changed one thing. That thing was the color of light being shined onto the plant. I put two cups of leaf bits into water next to each other and covered each with colored cellophane wrap. One was colored with blue and the other, yellow.
Anyway, what I learned today in bio class was that photosynthesis occurred much faster under yellow light than blue light. It wasn't even close. All 10 leaf bits in yellow light photosynthesized before one blue leaf bit could. There was no competition.
