Abstract: The purpose of this lab is to measure the rate of photosynthesis in isolated chloroplasts. The lab begins with adding solutions to multiple cuvettes, then adding either boiled chloroplasts, not boiled chloroplasts or no chloroplasts. After approximately 5 minute timed sessions in light, tubes are placed in spectrophotometer one at a time and the transmittance percentage is recorded for each test. Boiled chloroplasts are denatured, so photosynthesis cannot occur. Solutions in test tubes

Photosynthesis Lab * Intro: Photosynthesis is a process in which plants use sunlight to create glucose and oxygen byproduct from carbon dioxide and water. Photosynthesis involves a green pigment called chlorophyll. The formula for photosynthesis is 6CO2 + 6H2O ------> C6H12O6 + 6O2. Variables that can affect the process of photosynthesis include light intensity, temperature, and carbon dioxide levels. * Question: Do photosynthesis rates increase when more carbon dioxide is present

Introduction: In this lab a series of experiments were done to gain a greater understanding of photosynthesis, plant pigments and light absorption and transmittance by/through plant chlorophyll and accessory pigments. Photosynthesis is the process by which plants use energy from light (i.e. the sun, photons, electromagenetic energy), water, and carbon dioxide to produce ‘food’ for themselves, or some for of sugar, like glucose. Photosynthesis has two stages which take place within the chloroplasts

Photosynthesis Design Lab: Aim: To measure the effect of light intensity on the rate of photosynthesis in leaf discs. Background: Leaf disks float, naturally. When the air spaces are filled with a solution the overall mass of the leaf disks increase and they then sink. The solution used includes a small amount of Sodium bicarbonate (NaHCO3). This Bicarbonate ion acts as a carbon source for photosynthesis. As photosynthesis continues, oxygen is then released into the inside of the leaf disk which

Investigation 2 Paragraph 1 Based on the results of our photosynthesis experiment, we can state that each treatment of light, varying in intensity of the light source, were not significantly different from each other. The positive control at 2 feet away from the light source when compared to the treatment of higher intensity of light at 1 foot away from the light source had a p-value of 0.1778. The positive control when compared to the treatment of lower intensity of light at 3 feet away from

Introduction: Photosynthesis is one of the most fundamental processes that take place in plants and some other organisms. Photosynthesis converts solar energy into chemical energy of a carbohydrate (Mader & Windelspecht, 2013).The whole process takes place in the chloroplasts of green plant cells containing the pigment chlorophyll. Chlorophyll is one of the most important molecules in existence as all energy capture starts from there (Mader, 2010). If none of this pigment is in existence, plants

the air in order to survive every day. The oxygen that humans rely so heavily on is produced by plants in a process known as photosynthesis. Photosynthesis can be understood by simply looking at its equation. The equation for photosynthesis states that the reactants of carbon dioxide and water, with the use of solar energy, produce carbohydrates and oxygen. Photosynthesis is broken up into two types of reactions, the light reaction and the Calvin Cycle reaction. During the light reaction, pigments

Name _________________________________ Date _____________ Period ______ Lab: Investigating Photosynthesis and Cellular Respiration Background: All organisms are dependent on a healthy carbon dioxide-oxygen balance. Photosynthesis and cellular respiration are key processes in maintaining this balance. Plants, through the process of photosynthesis, use energy absorbed from sunlight, water, and carbon dioxide to produce sugars and oxygen. Animals and plants, through the process of cellular

as long as it was close to it. Then the test tube was placed inside the Erlenmeyer flask to which kept the test tube up right. After this was done the lab participant put together the “Apparatus” which consisted of the test tube with side arm inside the flask, a stopper, and HCl solution inside the test tube. The second step was for one of the lab participants placed the gas-generation solid that the teacher provided on to a balance to be weighed. This gas-generation solid was ¼ part of an Alka-Seltzer
