Floating disks photosynthesis experiment
WebExploring photosynthesis can be very difficult. But with this experiment, we can see the results of photosynthesis. In this experiment, we will use disks cut... WebThe TIME at which 50% of the leaf disks are floating (the median) is called the ET 50 (Estimated Time 50%). By interpolating on the graph (Figure 2), the 50% floating point is about 11.5 minutes. (Data show that, when comparing factors that affect the rate of photosynthesis, using the 50% point provides a greater degree of reliability and ...
