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

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

Biology Investigation Problem: How does light affect the rate of Photosynthesis? The Plan In my experiment I am going to see how light affects the rate of photosynthesis. To do this experiment I am going to set up the apparatus as shown in figure 1. The apparatus I am going to use are the following: - 1 Tripod 1 300ml Beaker 1 Boiling Tube 1 Clamp Stand 1Clamp 1 Boss 1 Ring Binder 1 Lamp 1 1 Metre Ruler 1 Thermometer 1 Stop Clock To do the experiment I will set up the apparatus first. I

: The purpose of the 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

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

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

Organisms through cellular respiration convert energy into ATP. They do this in three distinct stages; glycolysis‚the Krebs cycle and the electron transport chain. The Krebs cycle and electron transport chain are both aerobic process and require oxygen. In certain conditions where oxygen is not present or is low some organisms switch from cellular respiration into alcoholic or lactic acid fermentation. Fermentation is an anaerobic‚ metabolic pathway used to oxidize nicotinamide adenine

Lab 4: Photosynthesis and Chromatography of Spinach Leaves Discussion: The chromatography of the spinach leaves was taken to establish what pigments were present in the chloroplasts of the leaves. The solvent carried and separated the different pigments up the cellulose paper. The solvent moved up the paper because of capillary action because of adhesion of the solvent molecules and the paper. The pigments dissolved in the solvent also were carried up the paper and were separated because

A Study of Cellular Respiration & Gas Production in Peas We conducted this lab in order to determine the relationship between gas production and the cellular respiration rate between germinating peas and dormant peas. Cellular respiration is the procedure of changing the chemical energy of organic molecules into a form of energy that can be used by cells called ATP (adenosine tri-phosphate). Cellular respiration is conducted in 3 processes: Glycolysis‚ Citric Acid Cycle‚ and Oxidative

Photosynthesis and Semi-Conductor based Solar Cells Plants‚ by shear desire to survive have developed the worlds most efficient and reliable power supply by way of photosynthesis. Scientist for years have tried unsuccessfully to duplicate the process of photosynthesis. However‚ for the purpose of this paper‚ I will compare and contrast how energy and electricity is generated through photosynthesis and a semi-conductor based solar cell. In addition‚ this paper will explain how both processes
