determine the wavelength and light intensity effect on the reaction rate of photosynthesis. Photosynthesis is the conversion of light energy to chemical energy in the form of organic compounds. 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

Claire Graham BSC 2010L November 4th‚ 2015 Effects of Light Intensity and Wavelength on Photosynthesis of Spinach Leaves By replacing the air pockets in spinach leaf disks with a bicarbonate solution and allowing the disks to sit in the solution while being exposed to different light conditions‚ we were able to observe the effects of various light intensities as well as colors on the rate of photosynthesis. As the spinach leaves photosynthesized‚ oxygen pushed out the solution and filled the intercellular

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 radiation)

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

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

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

Biology lab: measuring the effect of light intensity on plant growth Aim: Investigate the effect of light intensity on plant growth Hypothesis: Light intensity will have an effect on plant growth. With an increase in light intensity there will be plant growth at a faster rate in comparison to when the light intensity is low where plant growth is limited and will take place slowly. When there’s too much light intensity‚ the light intensity will no longer become a limiting factor. A limiting

How light intensity effects the Rate of photo synthesis. Aim The aim of my experiment is to find out how light intensity affects the rate of photosynthesis. Prediction I predict that as the light intensity increases that the rate of photosynthesis will increase in proportion‚ so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant. There for the rate of photosynthesis will decrease proportionally with the distance of the light from the plant (in

Photosynthesis Lab Report Introduction The lights are essential for photosynthesis and it plays a major role. All the food we eat and all the fossil fuel we use is a product of photosynthesis‚ which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems. Photosynthesis is carried out by many different organisms but usually by plants and algae. All these organisms convert CO2 (carbon dioxide)
