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.
Measuring photosynthesis via the uptake of carbon dioxide. Using 'immobilised algae' - It's easy and accurate to measure the rate of photosynthesis and respiration using immobilised algae in hydrogen carbonate indicator solution-known as the 'algal balls' technique.here is a total of 7000 x 10 9 tonnes of carbon dioxide in the atmosphere and photosynthesis fixes 100 x 10 9 tonnes per year. So 15% of the total carbon dioxide in the atmosphere moves into photosynthetic organisms each year. There are a few key methods to calculate the rate of photosynthesis.
