grow rapidly‚ making it the ideal specimen for our experiment. It is hypothesized that altering the amount of light received by duckweed will alter its photosynthetic rate. It is predicted that a lower light intensity will lower the rate of growth in duckweed. Two treatment groups were covered with a screen in order to reduce light intensity. Both groups were kept under a controlled light source for fourteen days and plant counts were taken at regular intervals. The ravg for the experimental group

How does light intensity and carbon dioxide levels affect photosynthesis rate Phaladi Phaladi 201102379 Department Of Mathematics And Science Education University Of Botswana Plants‚ through the use of chlorophyll (green pigment in plants) that traps light can generate ‘food’ by combining carbon dioxide in the air and water. As with many chemical process energy is need to make and break molecules during the chemical process. The greater the light levels the more energy is available to carry

If i increase the intensity of the rate of photosynthesis would drastically increase which is the light bubbles would be emitted in the jar in one minute because of the fact that the more photons of light that fall on a leaf then more chlorophyll molecules would be ionised and the more ATP and NADPH are generated If i increase the intensity of the rate of photosynthesis would drastically increase which is the light bubbles would be emitted in the jar in one minute because of the fact that the more

Effects of Wavelength and Light Intensity on Photosynthetic Activity ABSTRACT The photosynthetic process of eukaryotes revolves around chlorophyll‚ the substance that give plants their green color. Plants convert light energy into chemical energy by means of photosynthesis. This experiment tests the reaction rates of a chloroplast suspension against variables of wavelengths and light intensity. Both a control and an experimental cuvette were exposed to a range of 450 to 750nm of light and varying

In conclusion‚ one can determine how photosynthesis is impacted by light intensity through the experimentation on ivy leaf disks in a bicarbonate solution. The function of the sodium bicarbonate in this experiment was to provide a sufficient amount of carbon dioxide (CO2) for the photosynthesis process to occur. Without CO2 or any of the other necessary reactants‚ glucose nor oxygen cannot be produced. The leaves rise and sink due to photosynthesis occurring in the plant cells. As the carbon from

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

INVESTIGATE A FACTOR AFFECTING THE RATE OF PHOTOSYNTHESIS. Introduction Photosynthesis is a chemical reaction which takes place inside the green plants (plants with chlorophyll‚ a pigment found in chloroplasts which causes the colour of the plants and it is the main photosynthetic pigment) and light energy is converted into chemical energy. Carbon dioxide‚ water and sunlight is transformed into sugar an oxygen‚ which later will be used as energy for the plant. The chemical equation of photosynthesis

duckweed Lemna minor‚ followed by its removal‚ was studied with 0.1–1.0 mg/L of Cu in a quarter Coïc and Lesaint solution at pH=6.1. In order to verify duckweed tolerance to Cu‚ photosynthesis was measured at the maximal concentration which caused no effect on the plant growth. The results showed that copper inhibited Lemna growth at concentrations ≥ 0.3 mg/L. At 0.2 mg/L‚ the final biomass was approximately four times greater than the initial biomass. Analysis of metal concentration in water showed

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
