    Based on the prompt above‚ “Investigate how light and darkness contribute to the cycling of carbon through both cellular respiration and photosynthesis of a plant” we devised a hypothesis that states‚ If we place the two test tube‚ one with carbonated water and the other regular water‚ with the Elodea inside a dark environment it will perform cellular respiration as it will not receive enough light energy to perform photosynthesis. From the result of our experiment we found that the test tube with

    to them. In prokaryotes instead of chloroplast they use their own cell membranes to do the job. Wavelength also has a role in photosynthesis because they have just the right amount of energy to excite chlorophyll electrons boosting them to a higher energy level. When summing everything up the reactants are carbon dioxide‚ water‚ and the suns energy and the process is light dependent and the Calvin cycle. The products include oxygen and glucose. Pigments serve as photosynthetic organisms that capture

    The rate of photosynthesis in each of the beakers will depend what is wrapped around the beakers such as red and blue cellophane‚ as well as the control of the experiment the beaker without cellophane. The cellophane will directly impact the light getting absorbed as well as the amount of CO2 in the beakers. Which overall as result will determine the final color of the water mixed with bromothymol blue. What was being measured was the color of the water after CO2 has been blown in the beakers. The
