Photosynthesis Lab Hypothesis

My hypotheses is that if I were to measure plant growth through different light stimulation then I would come to the conclusion that violet is best suited for maximum plant growth because on the light spectrum scale violet contains the most energy, then blue, cyan might possibly be reflected by plants do to its close proximity in color. The same would go for yellow and green would be completely reflected. Red would absorb well because it is a direct opposite on Newton’s color circle, just as green would be absorbed well into red.

I tested my hypothesis by conducting the experiment with varied colors of light and also by using several different types of plants. The controlled variable throughout the experiment was the three same plant seeds, and the variable that changed throughout the experiment was the color of light shining down on the plants.

My hypothesis concerning the light color violet was inconclusive due to the fact that i was unable to measure the plants, yet the data that I gathered from the other colors backs up the second half of my hypothesis.

My hypothesis concerning the light color violet was proven to be inconclusive due to the fact that I was unable to measure the plants grown by violet. Having said that though, the second half of my hypothesis was proven to be correct, referring to the light color blue and red. Even though red wavelengths are much weaker than blue ones, the red light kept an even pace with the blue and finished just short of it. So my hypothesis pertaining to the red being absorbed easily into the green because of the complete contrast in color was shown to be correct. Also my hypothesis that blue would produce some of the largest plants seemed to be correct as well.

I believe that if another experiment were to be conducted with the addition of white light, that the white light would prove to achieve maximum growth through the plants because of its mixture of all the colors....
