    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

    investigation I am going to establish the effect of changing light intensity on the rate of photosynthesis. What is Photosynthesis? Photosynthesis is how plants get their food. The reason why plants have leaves‚ roots or being green is all linked to photosynthesis. In photosynthesis‚ a plant takes carbon dioxide from the air and water from the soil and uses the light from sunlight to turn them into food. Photosynthesis occurs only in the presence of light‚ and takes place in the chloroplasts

    experiment was to 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

    The effect of nutrient concentration on duckweed growth Gina Neonakis Biology 203L:11 Biology 203:10 November 14‚ 2011 Abstract Lemna minor‚ or duckweed‚ is a small plant that floats on the surface of stagnant water that is usually rich in nutrients. Phosphorus is an important macronutrient in the growth of aquatic plants. We tested the effect of phosphorus on duckweed population growth using a control medium rich in nutrients and compared it to the population growth in a medium that lacked

    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

    Light Intensity Experiment: For the light intensity experiment‚ our first set of data illustrated strange correlations between the three tubes placed in front of a light source‚ so the data provided in e-campus was used. The tube that was 24 cm away from the light had the greatest decrease in absorbance over the course of 20 minutes‚ followed by the 30 cm and then the 49 cm light apparatus. The tube that was placed in the dark (wrapped in foil) remained a dark blueish-green color whereas the tubes

    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
