Measuring the rate of photosynthesis gcse

WebThey varied the distance of the plant from the light source. In the table below, the Rate of photosynthesis = Number of bubbles produced per minute. If we draw a graph of this … WebIn order to measure the rate of photosynthesis, we look at the amount of oxygen that a plant can produce, whilst changing one factor (e.g. light intensity). For example with this experiment above, you can investigate whether more oxygen bubbles are produced when more light bulbs are added. You would have to count the number of bubbles a minute.

WebInvestigating photosynthesis – starch and chlorophyll. During photosynthesis a plant absorbs light energy using the pigment chlorophyll. This allows it to convert carbon dioxide and water into glucose. This glucose is: transported to the growing parts of the plant for use in respiration; transformed into cellulose, proteins and oils WebThis procedure offers a method for measuring the rate of photosynthesis which depends directly on the rate of uptake of carbon dioxide by the photosynthetic organism. Hydrogencarbonate indicator changes colour with pH, which is determined by the concentration of carbon dioxide in solution. dj neus gonzalez https://jfmagic.com

WebGraph showing the effect of light intensity on the rate of photosynthesis At low light intensities, increasing the intensity will initially increase the rate of photosynthesis. At a certain point, increasing the light intensity stops increasing the rate. WebAug 17, 2024 · How do you measure the rate of photosynthesis GCSE? Count the number of bubbles emerging from the cut end of the stems in one minute. Repeat the count five times and record your results. Calculate the average number of bubbles produced per minute. Repeat the experiment at different distances away from the light source.
