How can you measure rate of photosynthesis
WebFactors affecting photosynthesis - light intensity. There are several ways of measuring the rate of photosynthesis in the lab. These include: the rate of oxygen production (number … Web1. One of the simplest measures of photosynthesis is just measuring how much your plants grow (i.e., weigh them). Of course this technique is imperfect because of other influences on growth, the amount of time you have to wait to get a measurable change, and ideally you would want to use the dry mass of your plants to avoid water content ...

Web21 de set. de 2024 · By measuring how many leaf discs are floating at consistent intervals, we can estimate the rate of photosynthesis. While we won’t be able to measure the rate at which oxygen molecules are created, the time it takes for the leaf chads to float is a much more readily observable proxy for the molar rate of the reaction. WebTo investigate the effect of light intensity on the rate of photosynthesis. Method Set up a boiling tube containing 45 cm³ of sodium hydrogencarbonate solution (1%).
