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

Plant Growth; Varying Light Exposures Intro and Hypothesis: The problem that is going to be answered is: will plant seeds grow at differently if they are covered by different materials while exposing them to the same amount of light? Also‚ which material will allow the plants to grow the most‚ tin foil‚ saran wrap‚ paper or no covering? Before the lab took place‚ it was hypothesized that the less light a plant receives‚ the less it will grow and the more light it receives‚ the more it will grow

Cells of all organisms are capable in acquiring the energy necessary to fuel chemical reactions for growth‚ repair‚ survival‚ and reproduction. Photosynthesis & cellular respiration are the main pathways of energy flow in living things. Photosynthesis is a process by which plants and some other organisms convert‚ light energy from the sun‚ CO2 from the air & H2O from the earth‚ into chemical energy stored in molecules like glucose. Cellular respiration is a process in which O2 is delivered to cells

respiration and photosynthesis are almost exact opposites. Photosynthesis is anabolic; it builds up glucose‚ or sugar‚ from light energy‚ water and carbon dioxide. The chemical equation for photosynthesis is: 6CO2 + 6H2O + Light Energy C6H12O6 + 6O2. Cellular respiration‚ on the other hand‚ is catabolic. It breaks down glucose to form carbon dioxide and water. The chemical equation for cellular respiration is: C6H12O6 + 6O2 6CO2 + 6H2O + 38 ATP. Cellular respiration and photosynthesis follow the

High-fat Diet Contributes to Aggressive Behavior Hypothesis: High-fat diet contributes to aggressive behavior. Introduction: Aggression is a behavior that is destructive‚ hostile or violent and is intended cause harm‚ injury or damaged to the target person or object. Aggression and violence are the major problems in our society and one of the main contributions of this behavior is socioeconomic status (SES). According to the American Psychological association (APA)‚ socioeconomic status is

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

The five-step processes for hypothesis testing are the following. Step1. Specify the null hypothesis H0 and alternative hypothesis H1. The null hypothesis is the hypothesis that the researcher formulates and proceeds to test. If the null hypothesis is rejected after the test‚ the hypothesis to be accepted is called the alternative hypothesis. For example if the researcher wants to compare the average value generated by two different procedures the null hypothesis to be tested is [pic] and

Primordial Soup Hypothesis is a hypothesis created by Alexander Oparin in the year of 1942. It claims that life started when a group of chemicals mixed together to form a pond‚ making amino acids‚ which then lead to proteins‚ and later the first forms of life. The evidence presented in the Miller-Urey experiment provided proof that basic monomers could be created from a mixture of methane‚ ammonia‚ and hydrogen. Different to the Primordial Soup Hypothesis‚ the Iron-Sulfur World Hypothesis states that
