Abstract Duckweed is a small aquatic plant that is able to 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

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

Feed Industry Overview: Duckweed feed has been found to be a very nutritious feed source for many types of livestock. The fact that duckweed can be fed to animals in its wet form or dried for a more concentrated food source make an efficient‚ cost effective‚ harvester a possible attractive product for this market. Traditional Harvesters are economically unfeasible and manual harvesting is very labor intensive for medium to large scale operations. Feed prices can vary drastically due to crop

Conclusion In this experiment I tested different light intensities. I tested a normal fluorescent light bulb‚ a 100-watt light bulb‚ a 25-watt light bulb‚ and a 15-watt light bulb. I was surprised to find that the control plant grew the most at 135 mm. The 100 watt plant grew the least at 0 mm due to the fact that it fried the plant. The 25 watt plant grew the next highest at 120 mm. The 15-watt light bulb grew tall fastest‚ but then slowed down and stopped at 98 mm you would want to use this

Research question : How does the different light intensity affect the rate of photosynthesis in plants? Objective : To investigate the relationship between different light intensity (by having the source of light at different distance to the plant discs which is at; 10cm‚ 15cm‚ 20cm‚ 25cm‚ 30cm‚ and 35cm ) and rate of photosynthesis of plant. Introduction : Photosynthesis is the process where light energy is absorbed by green plants to convert the raw materials (carbon dioxide and water) into

The Effect of Light Intensity The effect of different light wavelengths was tested in the following experiment. The rate of photosynthesis can be affected depending on the light treatment it receives. With the aid of DPIP acting as NADPH in photosynthesis‚ it was possible to observe the reaction as it took place. Samples were created with dark‚ 24 cm‚ 30 cm‚ and 49 cm light treatments. The absorbance was measured in five-minute intervals for each sample and recorded in an appropriate table

Light Intensity Characteristics of Photocells The photoelectric effect is defined as the emission of electrons from a material by visible light. The cadmium sulfide photocell is used to act as a conductor once exposed to light‚ allowing light to travel through. However it also acts as an electric resister (an opposition to a current flowing in a circuit) once not exposed to light. The photocell serves today ’s cause in a sufficient manner. It is used for a variety of reasons but it is mainly
