The effects of Light Quality on the Rate of Photosynthesis Measure through Floating Spinach Disks

Abstract This study was undertaken to determine the relationship of different wavelengths of light and the rate of photosynthesis in spinach leafs. The rate of photosynthesis was measured every five min under light colors of white, green, red, blue and yellow under a light intensity of 2000 lux. The rate of photosynthesis was measured by the spinach disk method in which we replaced the air from the disks with sodium bicarbonate using a vacuum. Under photosynthesis, …showed first 75 words of 2444 total…

It would be interesting to see the photosynthetic rate when the disks are actively floating to the top which occurred mainly in the first ten min. By taking more readings we could develop a better graph. Literature Cited Freeman, S. 2002. Biological Science. New Jersey: Prentice Hall.
