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

Chlorine in Photosynthesis Experiment Abstract Photosynthesis the means by which green plants and different types of organisms use light from the sun to synthesize foods from CO2 and H2O. Chlorine is a chemical element usually in the form of a yellow-green gas and is a strong oxidizing agent. Elodea is a type of aquatic plant also known as waterweed that is native to North America. In the experiment that took place‚ the effect of chlorine in the presence of photosynthesis reactions were studied

Based off the results from this lab the student was able to determine and have an overall better understanding of the variables that affect the rate of photosynthesis in a plant. The first variable the student tested in the lab was 30cm of light with CO2 present. The student started this trial with all 10-leaf disks and timed how many leaf disks came up every minute for 15 minutes. One minute into the trial and the student recorded that no leaf disks had yet to rise to the top of the solution. At

The Rate Of Photosynthesis: Lab report 1) Construct a graph of your data 2) Using the graph‚ estimate the time at which 50 percent of the leaf disks were floating on the surface. The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute. At the 10th minute our number rose up to

Photosynthesis Investigation Research Question How does length of pondweed affect the amount of bubbles produced in 2 minutes by pondweed during the process of photosynthesis? Independent variable: Length of pondweed (8/10/12 cm). Dependent variables: amount of bubbles produced in 2 minutes. Control variables: Volume of water in the beaker (500ml)‚ The volume of water has to be the same every time‚ so when doing the experiment I need to make sure I always use these 500 ml that i have already

Photosynthesis is the process which plants use to change Carbon Dioxide and water into sugar by using the sunlight. Photosynthesis usually take place in plants cell such as chloroplast. In this lab experiment‚ we used sodium bicarbonate to influence photosynthesis. Sodium bicarbonate is a formula of NaHCO3 (baking soda). In this lab experiment‚ we observed photosynthesis in spinach leave and investigated the effect of sodium bicarbonate on photosynthesis. The experiment was to determine how many
