Since the middle of the 19th century the level of carbon 1. the relationship of different wavelengths of light and the rate of photosynthesis in spinach leafs. If a plant is continually left in the light or in the path of a fan wind then it will lose the most mass through transpiration out of all of the plants because light promotes more photosynthesis to occur which requires the intake of CO2 and the release of water through the stomata. Introduction This experiment was performed to test the following hypothesis Green color light will have the least amount of photosynthesis than the other colors. carbon dioxide water light energy gt glucose oxygen. Photosynthesis process requires several factors such as Light Intensity Increased light intensity results in a higher rate of photosynthesis. To adequately explain your result in your lab reports you will need to discuss some of the factors that affect the rate of photosynthesis in a leaf and thus the appearance of the light response curve. Rate is the change occurring over time. To fully address the performance expectation students need to develop an understanding of the mechanism of photosynthesis. It increases the temperature of the leaves. Since DPIP has a dark blue color DPIP was used during the lab to show that photosynthesis was occurring in the cuvettes. In my hypothesis I had predicted that photosynthesis rate will increase in the plant discs under the red and blue lights causing an increase in the number of floating discs after the period of time of 10 minutes compared to other colors of light due to the fact that the pigments in a plant chlorophyll a chlorophyll b and carotene used red is more effective than its counterparts most likely because red light has a. 1985. We can now modify the photosynthesis equation to the following red and blue light. Red light has longer wavelengths than blue light and is therefore a lot less energetic. com pub shockwave cabs flash swflash The light 39 s wavelength energy similarity to the dominant pigment and how much each pigment is devoted to each color are all factors in determining how efficient light is in photosynthesis. was determined using the Warburg manometric method. 25 Sep 2017 By doing so I will be able to keep the room temperature relatively the same throughout the experiment reducing the effect of temperature increase nbsp Prediction The blue light will have faster floating leaf disks than the red yellow and green lights. long wavelength that allows it radiate more energy and heat than other colors.

Purpose The purpose of this project is to show that different colors of light Light supplies the power to carry on photosynthesis the food making process in leaves . We are using 2 kinds of light bulbs which are the 40 watt one and the 60 watt one. The water in the flask acts as a heat sink by absorbing most of the light s infrared radiation while having little effect on the light s visible radiation. Based on your knowledge of photosynthesis how would you expect the color of the light to effect the movement of electrons. Flood Light Water Heat Sink Cuvettes . 1. Xu and C. The green light would have the slowest rate because the chlorophyll inside of the leaves reflects green light so it would not be absorbed as much as the other colors. by using a hot plate. This is because these things are what a plant needs in order to photosynthesize. Which pigment reflected an orange color VI. B. The light that is absorbed the best is blue so this shows the highest rate of photosynthesis after which comes red light. Before they begin the experiment however students must come up with a well worded hypothesis to be tested. Method Set up a boiling tube containing 45 cm of sodium hydrogencarbonate solution 1 .
