The rate of photosynthesis can be measured by measuring the production of oxygen gas, a product of the reaction. This can be done by collecting the gas released by a plant and measuring its volume over a certain period of time. Similarly, the rate of cellular respiration can be measured by measuring the consumption of oxygen gas, a reactant of the reaction. This can be done by measuring the decrease in the volume of oxygen gas in a closed system over a certain period of time.
