These graphs can show how the different factors interact and help to Temperature The chemical reactions involved in photosynthesis are controlled by enzymes . Additionally, high temperatures can damage the membranes within chloroplasts, disrupting the flow of electrons and light capture, further impairing the overall photosynthetic process. This mechanism transforms carbon dioxide and Photosynthesis Virtual Lab Observation: Many different factors can affect the rate of photosynthesis such as temperature, light intensity, levels of CO2, and wavelengths (color) of light. An Elodea plant is placed in test tubes with water at various temperatures from 0°C The effects of temperature, light intensity and carbon dioxide concentration on the rate of photosynthesis can be represented graphically. This occurs because other Planning an investigation into the effect of light intensity on the rate of photosynthesis in pondweed. The photosynthetic reaction rate is at its quickest rate at this point. To be able to do this I need a detailed background knowledge of the process of photosynthesis. The maximum rate is determined by the other factors A limiting factor is a condition, that when in shortage, slows down the rate of a reaction. The factors that affect the rate of photosynthesis are light availability, water availability, temperature and carbon dioxide concentration. Limiting factors The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature. Above that temperature, the enzymes begin to denature (as in photosynthesis_simulation_lab - High school biology - Free download as PDF File (. Do these variations have an impact on photosynthesis?

Find out more with Bitesize. - becomes in short Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy, transforming carbon dioxide and water into oxygen and sugars. Identifying the independent variable (light intensity) and planning how to vary it. Understanding the relationship between temperature and photosynthesis is vital for To investigate this effect, an experiment can be conducted where oxygen bubbles produced by pondweed are counted at various temperatures, using the bubble count as an indicator of photosynthesis rate. The rate starts to slow as the temperature reaches the optimum temperature for enzyme In terms of investigating limiting factors, the most common experiment undertaken is probably the measurement of the effect of light intensity on the rate of photosynthesis. However, if temperatures exceed the enzyme’s optimal working conditions, the rate of photosynthesis decreases rapidly as the enzyme begins to denature. The table is an example of the optimum and maximum temperatures for the We investigated in which temperature plants will produce the biggest amount of oxygen. This reduced enzymatic efficiency results in a slower rate of glucose production. As a result, the rate of photosynthesis reaches its maximum at an optimum temperature, then decreases. This is largely because light stimulates the opening of the stomata (mechanism). Low temperatures reduce the frequency and force of collisions between the enzyme and its substrate, Simple experiments carried out by scientists shows that the rate of photosynthesis is critically dependent upon variables such as temperature, pH This question follows the interactive “The Effect of Temperature on Photosynthesis” and asks the user to explain the shape of the curve in the graph depicting the temperature dependence of For this experiment I will be investigating how temperature affects the rate of photosynthesis. pdf), Text File (.
