Abstract the purpose of this experiment is to observe the factors affecting the photosynthetic rate of leaves, which is measured in two ways. Big idea investigation 5 t95 cellular processes: 2 energy and communication investigation 5 photosynthesis what factors affect the rate of photosynthesis in living leaves. 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. Lab: what affects the rate of photosynthesis duration: 45 min class size: up to 32 students general overview: in this lab, students will make hypotheses about how different. How does the level of light affect the rate of photosynthesis question date: 2014-11-03: answer 1: in photosynthesis, the energy from the sun is used to turn carbon dioxide (co 2) and water. Photosynthesis lab what is the effect on the rate of photosynthesis of spinach leaves when they are in an environment of different concentration of carbon dioxide.
The measured rate of photosynthesis as a function of absorbed wavelength correlates well with the absorption frequencies of chlorophyll a, but makes it evident that there are some other. Study photosynthesis in a variety of conditions oxygen production is used to measure the rate of photosynthesis light intensity, carbon dioxide levels, temperature, and wavelength of light. An increase in the amount of co2 well increase the rate of photosynthesis how does the rate of photosynthesis relate to carbon dioxide levels update cancel. C3 photosynthesis plants which use energy that has been collected from the light, and causes the rubisco to operate at perhaps a quarter of its maximal rate. In the photosynthesis investigation, you will compare the photosynthetic light response curve of your leaf to that studied by another group to adequately explain your result in your lab.
As light intensity increases, the rate of photosynthesis will increase up until a certain point, when photosynthesis is proceeding at its maximum rate. 244 madison avenue, 10016-2817 new york city, new york, usa.
Thus the overall effect of temperature on photosynthesis is that it increases with temperature to an the rate of photosynthesis in relation to temperature. Several days of cloudy weather can slow the rate of photosynthesis, resulting in lower oxygen production within a waterbody.
Get expert answers to your questions in plant biology, photosynthesis, chlorophyll and carotenoids and more on researchgate, the professional network for scientists.
Count the number of oxygen bubbles given off by the plant in a one -minute period this is the rate of photosynthesis at that particular concentration of co2. Free photosynthesis process review study chloroplasts, the chemical equation, chlorophyll and the light and dark stages of photosynthesis. Lab 5 photosynthesis: why do temperature and light intensity affect the rate of photosynthesis in plants introduction you have learned that green plants have the ability to produce their. Photosynthesis, generally, is the synthesis of sugar from light, carbon dioxide and water, with oxygen as a waste product it is arguably the most important biochemical pathway known nearly. Photosynthesis: photosynthesis from the air to make carbohydrates in photosynthesis over millions of years is being returned at an incredibly rapid rate. Biology news & research we expect that our experimental plant will have higher rates of photosynthesis and hence a higher rate of growth than normal plants. The rate of photosynthesis markedly increases with an increase in temperature provided other factors such as co 2 and light are not limiting.
Does light intensity affect the rate of photosynthesis in elodea plants hypothesis: yes, light intensity does affect the rate of photosynthesis too much light may cause plants to burn. Science fair project which compares the rates of photosynthesis for various light sources which type of light will be best for photosynthesis and why. If the ph is too high or too low, the rate of photosynthesis will decrease if the ph is just right, the rate will increase to the best possible point photosynthesis is the process by which. Photosynthesis is the process by which plants take carbon dioxide from the atmosphere, add water, and use the energy of sunlight to produce sugar.
