Photosynthesis and Cellular Respiration Photosynthesis and respiration are reactions that complement each other in the environment. In reality, they are the same reactions, but they occur in reverse. During photosynthesis, carbon dioxide and water yield glucose and oxygen. Through the respiration process, glucose and oxygen yield carbon dioxide and water. They work well because living organisms supply plants with carbon dioxide, which undergoes photosynthesis and produces glucose, and these plants and bacteria give out oxygen, which all living organisms need for respiration. Photosynthesis and respiration can be illustrated as follows: Photosynthesis Carbon Dioxide (CO2) + Water (6H2O) + Light energy Glucose (C6H12O6) +…show more content…
During photosynthesis, glucose is produced from converted sunlight energy by plants. In general, the more light, the faster the rate of photosynthesis. However, research many years ago demonstrated that increased light intensity only increased the rate of photosynthesis up to a certain point. Therefore, the relationship of photosynthesis and cellular respiration is nonlinear (Biggs, Edison, Eastin, Brown, Maranville, & Clegg, 1971). Scientific Method It is not uncommon for scientists to encounter a problem that cannot be explained. As a result, scientists use another fundamental process that is referred to as the scientific method. What is the scientific method? The scientific method is a way to probe into science by asking questions in a systematic way, which generates a hypothesis with the ultimate goal of improving the understanding of the problem. The following are the steps of the scientific method: Background and observation Generate a hypothesis Conduct an experiment based on the hypothesis Data analysis and results Share your conclusions with the scientific community Question: Is it possible to examine the relationship between photosynthesis and cellular respiration under controlled experimental conditions? Explain your response in detail. Model Answer It is not uncommon for scientists to encounter a problem that cannot be explained. As a result, scientists use another fundamental process that is
