Photosynthesis and Semiconductor-Based Solar Cells Photosynthesis‚ by definition‚ is “the process by which green plants and certain other organisms transform light energy into chemical energy” (photosynthesis‚ 2011). This is a remarkable process that occurs naturally and is one that is required for all living organisms to sustain existence on this planet. The efficiency of this process has sparked inventions‚ such as the semiconductor-based solar cell‚ that would allow humans to produce energy

Photosynthetic Activity in Plants Using Different Wavelengths of Light and Pigmentation Abstract The roles played by light and pigmentation in photosynthesis were examined in the geranium and Coleus plant. In addition‚ the separation of certain pigments based on their molecular structure was also examined‚ with the use of paper chromatography. When different leaves of the geranium plant which were exposed to different wavelengths of light‚ photosynthesis proved to be most actively present in

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

Both photosynthesis and cellular respiration are the main pathways of energy transportation in organisms. However‚ the reactants and the products are exact opposites in photosynthesis and in cellular respiration. In photosynthesis‚ cells take in carbon dioxide (CO2) and water (H2O) by absorbing energy from the sun‚ and then the cells release oxygen (O2) and store glucose (C6H12O6). The formula of photosynthesis is: Light energy 6CO2+6H2O → C6H12O6+6O2

ADI Lab investigation: Photosynthesis Introduction and goals: In our experiment we worked with photosynthesis‚ which is the process of light energy‚ CO2 and H2O being turned into food for the plant. CO2+H2O+ Light energy=C6H12O+O2 is the formula for photosynthesis. Our group hypothesis was trying to determine weather o2‚ water‚ or the nutrients of the soil determine the mass of the water. The guided question was “Where does the mass that makes up a plant come from?” Methods:

our class has discussed the topic of the human condition. The dictionary definition of the human condition is “the positive and negative aspects of existence as a human being‚ esp. the inevitable events such as birth‚ childhood‚ adolescence‚ love sex‚ reproduction‚ aging and death.” (dictionary.com) My definition of the human condition‚ is similar to this‚ but also how everyone is different‚ and all have a different views‚ and everyone is different in their own way.
