In the past, people were accustomed to writing in vertical lines from right to left. The traditional couplets followed this rule, but things have changed. Sometimes people don't follow the rules, and they even make mistakes. Here is the way to read Spring Festival Couplets: First, look at the horizontal scroll. 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.
The number of bubbles released in a given time can be counted as a measure of the rate of photosynthesis. The apparatus in the diagram shows how the volume of oxygen produced in a given time may be measured instead. In this experiment, move the syringe to draw the oxygen produced into the capillary tubing.reen plants absorb light in their leaves and convert it to energy by photosynthesis. Temperature, carbon dioxide concentration and light intensity can affect the rate of photosynthesis. 1  1. 2  2.
