# limiting factors of photosynthesis graphs

Basicly, the rate of photosynthesis will decrease if Carbon dioxide, light intensity or tempearture is not sufficent. Graph 8 Chlorophyll as a limiting factor. A by-product of photosynthesis is oxygen. We cover the word equation (and symbol equation) which describes the process. Criticism of Law of Limiting Factors. They may use artificial light so that photosynthesis can continue beyond daylight hours, or in a higher-than-normal light intensity. the limiting factor here isn't temperature because it's the same for both graphs. If we change the limiting factor the rate of photosynthesis will change but changes to the other factors will have no effect on the rate. The law states that the rate of a physiological process will be limited by the facotr which is in shortest supply. meg-c123; Subjects. the graph at 0.4% carbon dioxide levels off at a higher point than the one at 0.04%, so carbon dioxide concentration must have been a limiting factor at 0.04% carbon dioxide. A tutorial explaining how each of the three major factors which limit the rate of photosynthesis. Graphs are useful to demonstrate this: The graph above shows that as the light intensity increases, so does the rate of photosynthesis. photosynthesis rate involving two or three factors and decide which is the limiting factor. Limiting factors of photosynthesis This resource is designed to help students to describe and explain the patterns shown in graphs and uses the context of rates of photosynthesis. Any one of these could become a limiting factor. Graphs are useful to demonstrate this: The graph above shows that as the light intensity increases, so does the rate of photosynthesis. The more CO2 a plant is given, the faster it can photosynthesise up to a point, but then a maximum is reach. Suitable for mid and higher students in KS3 (possible KS4). What is the limiting factor for this graph? Usually, only one of these factors will be the limiting factor in a plant at a certain time. Worksheet filled in whilst they teach each other and exam questions to reinforce knowledge. A : This is the easy one remember. The usual atmospheric level of CO2 is 0.03%. extract and interpret graphs of photosynthesis rate involving one limiting factor; The most commonly used method to measure the rate of photosynthesis is to measure or observe the oxygen released from aquatic plants; Diagram showing the setup for the investigation using aquatic plants. (f) the roles of respiration, combustion and photosynthesis in the maintenance of the levels of oxygen and carbon dioxide in the atmosphere; WJEC Combined science. According to this law, when a process depends on a number of factors, its rate is limited by the pace of the slowest factor. C Another factor, such as light intensity, is limiting the rate of reaction. The graph demonstrates a strong correlation between the rate of photosynthesis peaks and the absorption peaks. So my textbook says (referring to a graph regarding rate of photosynthesis); Initially an increase in light intensity causes an increase in rate of photosynthesis. answer choices . Learn how the rate of photosynthesis is affected by light intensity, carbon dioxide concentration, and temperature. In this graph, the rate of photosynthesis is controlled by carbon dioxide levels. Photosynthesis will not be able to occur any faster. Start studying Rate of Photosynthesis (graphs). Any change in the level of a limiting factor will affect the rate of reaction. Without enough light, a plant cannot photosynthesize very quickly, even if there is plenty of water and carbon dioxide. Read the graph accurately and reference the data in the question. The effect of light intensity on the rate of photosynthesis The factors which could be limiting the rate when the line on the graph is horizontal, include temperature â¦ Photosynthesis Lab . answer choices . Plants use some of the oxygen they produce, but most of it is released. Bean plants produce more ATP than corn plants. A worksheet which can be used during lessons on the three main limiting factors of photosynthesis. This means that the factor directly affects the rate of photosynthesis on its own, regardless of the level of the other factors.
