If the four characters are written from left to right, the upper scroll will be on the left and the lower scroll on the right.
The input of water cannot estimate photosynthetic rate, since it is also used in transpiration. The parameter that you chose to measure depends on your resources and the accuracy required of your estimates. There are instruments that measure the input of CO2 and output of H2O, called Photosynthesis Measurement Systems.
In this experiment the rate of photosynthesis is measured by counting the number of bubbles rising from the cut end of a piece of Elodea or Cabomba.he students can be allocated to investigate a particular factor that affects the rate of photosynthesis, or they can choose from this list, or they can develop their own ideas. 1  Light intensity or distance of the Elodea from the lamp. 2  Temperature of the water. 3  Carbon dioxide concentration. 4  Acidity: use buffer solutions to maintain different pHs. 5  Co
