Explanation:
Detailed explanation-1: -By actually measuring the volume of oxygen gas produced by a plant, you can work out the rate at which photosynthesis is happening. The more oxygen given off, the higher (or faster) the rate of photosynthesis.
Detailed explanation-2: -3.8. 7 Explain that the rate of photosynthesis can be measured directly by the production of oxygen or the uptake of carbon dioxide, or indirectly by an increase in biomass.
Detailed explanation-3: -Finally, photosynthesis can be measured through an increase in biomass. If batches of plants are harvested at a series of times and the biomass of these batches is calculated, the rate increase in biomass gives an indirect measure of the rate of photosynthesis in the plants.
