In 3-5 sentences, explain how the rate of photosynthesis or cellular respiration can be measured using products or reactants. explain simply and briefly

The rate of photosynthesis can be measured by monitoring the production of oxygen or the consumption of carbon dioxide, which are the products and reactants of the process, respectively. By measuring the amount of oxygen released or carbon dioxide taken in over a given time, the rate of photosynthesis can be determined. Similarly, the rate of cellular respiration can be measured by monitoring the consumption of oxygen or the production of carbon dioxide, which are the reactants and products of the process, respectively.

use simpler terms

We can measure the rate of photosynthesis by checking how much oxygen is produced or how much carbon dioxide is used up. Oxygen is made during photosynthesis, so if we measure the amount of oxygen released, we can tell how fast photosynthesis is happening. In the same way, we can measure the rate of cellular respiration by checking how much oxygen is used up or how much carbon dioxide is made. Oxygen is used up during cellular respiration, so by measuring the amount of oxygen consumed, we can determine the rate of cellular respiration.
