SCIENTIFIC REPORT ON THE EFFECT OF WAVELENGTH ON PHOTOSYNTHESIS Red wavelengths will increase the rate of photosynthesis to a greater degree than blue or green wavelengths and thus will be the most optimal for plant growth. This hypothesis will be tested under laboratory conditions using silver beet extracts and DCPIP under different wavelengths and assessing the photosynthetic qualities using a spectrometer at 605nm. Photosynthesis is the process by which the suns visible light (electromagnetic

There are two phases in photosynthesis‚ the light reaction and dark reaction. The following experiment tested only the light reaction. Photosynthesis takes place on the chloroplast‚ and the chloroplast contains chlorophyll pigments which absorb light energy. Pigments are particular to different wavelengths. The following

The effects of different wavelengths of light on the rate of photosynthesis Introduction This experiment was performed to investigate the effects of different wavelengths of light on the rate of photosynthesis. If a multiple colored film petri dishes are place under a 50 watt lamp‚ then the rate of photosynthesis will be greater for those with red‚ blue and clear film‚ than those with green and black film. We believed the petri dishes with the red‚ blue and clear film would produce the best

product of photosynthesis‚ which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems2. Many organisms are not able to use the energy obtained from sunlight directly; however‚ plants are able to use this energy and convert it into chemical energy by converting CO2 (carbon dioxide) and H2O (water) to organic materials3. The energy source for photosynthesis comes from sunlight‚ which allows for the fuel that drives photosynthesis. This process

Introduction: The rate of photosynthesis varies greatly with changes in wavelengths of light. Light’s colour is determined by its wavelength of light‚ and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a plant called Elodea (pond weed). Elodea is native to North America and it is also widely used as aquarium vegetation. The basic structure of these plants are whirls of leaves around

Title and Author 1. The Effect of Extreme Temperatures on the Rate of Photosynthesis 2. Jeffrey Xia 2. Abstract A previous lab in which we conducted‚ tested whether or not the light intensity had an effect on the rate of photosynthesis. We concluded that light intensity did possess an effect on the rate of photosynthesis – the closer the experimental plant units were to the light source‚ the more experimental plant units exhibited the effect of gas exchange in photosynthesis. Therefore‚ in this

The Effects of Light Intensity on the Rate of Photosynthesis Aim: To investigate the effects of light intensity on photosynthesis. Background: Photosynthesis is a process that plants undergo to produce glucose. The plant then uses the glucose to produce energy which the plant needs to sustain life. The chemical formula for photosynthesis is: Sunlight 6CO2 +6H2O → C6H12O6 + 6O2 Chlorophyll The plant requires light‚ carbon dioxide and

THE EFFECTS OF CIGARETTE SMOKE TO PHOTOSYNTHESIS Increased Carbon Dioxide Smoke of all kinds‚ including cigarette smoke‚ increases the amount of carbon dioxide where it is present (since smoke is itself produced via combustion). Plants use carbon dioxide to make sugars (during photosynthesis). Its increased abundance‚ therefore‚ makes it easier for the plant to obtain. Thus‚ smoking near a plant actually makes it easier for that plant to obtain much-needed carbon dioxide. Hampering Photosynthesis
