Measuring the rate of photosynthesis gcse
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 WebGCSE Science Measuring the rate of photosynthesis Plan I am going to investigate the factors that affect the rate of photosynthesis, these factors are: CO2 Colour of the light …

WebSep 5, 2024 · Measuring the Rate of Photosynthesis photosynthesis experimental-design bioenergetics measurement experiment 1,847 One of the simplest measures of photosynthesis is just measuring how much your plants grow (i.e., weigh them). 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.
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. 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 …
WebA potometer can be used to measure the rate of transpiration that’s proportional to water uptake. Transpiration cannot be measured directly as some of the water will be used in … WebPhotosynthesis is a chemical reaction that takes place in the leaves of green plants building up food compounds from carbon dioxide and water, and using the energy from sunlight, which is absorbed by chlorophyll. The chemical equation for the reaction of photosynthesis is: - chlorophyll 6C02 + 6H20 → C6H1206 + 602 Carbon water light glucose oxygen
