How do you measure the rate of photosynthesis?
ANSWER 1get a beaker full of water then put the plant into it with a test tube of water on it. then put some light an it and blow into the water with a straw. if you see bubbles building up in the tube then you have oxygen.ANSWER 2Hi photosynthesis measurer,Counting the air bubbles that are produced when a plant is in water is perfect for measuring the rate of photosynthesis if you have limited resources and only need rough estimates. However, since bubbles have a variable, undefined volume, counting the number of air bubbles is not precise. You can obtain slightly more accurate results by collecting the air released, and measuring the volume.If you wish to obtain precise and accurate measurements of the rate of photosynthesis, you could use a Photosynthesis Measurement System. They are instruments that quantitatively measure the rate using an infrared gas analyser to assess the input of CO2 and output of H2O. Some Photosythesis measurement systems (such as the LCpro+) offer the ability to precisely control the environment of the leaf being measured. These instruments maintain the leaf chamber at user-selected concentrations of CO2 and H2O, and can control PAR and temperature. This allows you to conduct detailed experiments on the effects of different conditions on the rate of photosynthesis.Photosynthesis measurement systems are designed to be portable so you can carry them to field sites (except some models are somewhat heavy for field work. LI-COR's 6400 model weighs 13.5kg!).Answer 3Below is a reference site that might be helpful.
