WebbMeasuring photosynthesis by oxygen evolution In this experiment you are going to use the aquatic plant Cabomba to observe bubbles of oxygen which are released as the plant carries out photosynthesis. These bubbles can be counted and the rate of bubbling can give you an indication of the rate of photosynthesis. WebbOne of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. This reliable and enjoyable practical gives students the opportunity to observe the different pigments involved in photosynthesis using thin layer chromatography (TLC).
