The lamp experiment is primarily based off of the process of photosynthesis. The experiment tracks the rate of photosynthesis as it is affected by the color of the light source. Changing the light bulb color changes the length of the wavelengths that hit the chloroplasts in the plant leaves and effects how fast or if photosynthesis occurs. The equation for photosynthesis is 6 CO2 + 6H2O + light energy=C6H12O6 + 6O2 meaning that when a plant cell absorbs carbon dioxide and water alongside sunlight

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

This lab was split up into two different experiments‚ using different variables in each. During the first section of the lab‚ we investigated the what the effect of light is on both photosynthesis and cellular respiration. Our hypothesis about this effect was that the cuvette representing ‘no light’‚ being covered in foil‚ would result in a yellow CO2 indicator fluid‚ meaning that there was a decrease in pH and a high level of CO2 was present. Additionally‚ we hypothesized that the cuvette that was

Photosynthesis and Cellular Respiration lab makeup Photosynthesis absorbs energy from the the sunlight ‚and water‚and carbon dioxide to to create energy sugar ‚and oxygen. Photosynthesis also absorbs molecules that are called pigments. The process of photosynthesis is used by plants to make food for themselves. By then doing this‚ it also benefits us humans and animals by releasing carbon dioxide. Oxygen to them is considered a waste product‚ but a necessity to us. The photosynthesis

Chapter 6/7 Photosynthesis and Cellular Respiration Review 1. _Energy__ is required for transport of certain materials‚ movement‚ growth‚ and reproduction. 2. Define autotroph and heterotroph. Name the organisms that make up each. Autotrophs use the suns energy to produce their food. Heterotrophs consume other organisms to obtain food. Plants Animals 3. ___Sun__ is the ultimate source of energy for all living things on Earth based on the cycle of photosynthesis and cellular respiration

investigate the effect of carbon dioxide concentration on the rate of photosynthesis Introduction Photosynthesis is a process that is essential for every living organism. Organic substances‚ such as glucose‚ are made from carbon dioxide and water by light energy from the sun. The light energy is absorbed by chlorophyll and converted to chemical energy. During the process‚ oxygen is released as a by-product. The rate of photosynthesis is affected by a few of factors‚ including light intensity‚ temperature

Photosynthesis: Plant cells vs. Solar Cells Chevon Allen 01/23/2010 SCI-115 Professor Garcia Photosynthesis and the semiconductor-based solar cell are very similar process with different ways of reaching the same goal. In photosynthesis‚ plant cells harness the solar energy of the sun with carbon dioxide to transform water molecules into hydrogen‚ oxygen‚ and electrons. Just like photosynthesis‚ Semi conductor based solar cells harness the solar energy of the sun for the same purposes

3.2 DNA Extraction The DNA will be extracted from the Nemipterus samples according to Wizard® Genomic DNA Purification Kit (Promega) protocols. The first step of is cells and nuclei will be lysed by adding 120 µl of 0.5 Molar ethylenediaminetetraacetic acid (EDTA) to 500 µL of Nuclei Lysis Solution in a eppendorf tube‚ then it will be chilled on ice until the solution turn cloudy. The second step is 0.5 cm of Nemipterus sample tissue will be minced to fine powder. The fine powder of fresh Nemipterus

In the Calvin cycle‚ getting pulled into the cells using RUBISCO to facilitate the process incorporated gaseous CO2 molecules. RUBISCO acts much like a sponge with a great absorptive power to suck up the CO2 from the air surrounding a plant. Photosynthesis is a process used by plants and other organisms to convert light energy‚ normally from the Sun‚ into chemical energy that can be later released to fuel the organisms’ activities. When light hits an object‚ it is absorbed or reflected. When it
