Did you know?
WebIn order to measure the effect of light on photosynthesis, it is necessary to use a gas exchange system to measure the rate at which oxygen is produced as a byproduct of photosynthesis. This can be done using a device called a respirometer, which measures the volume of oxygen produced over a given period of time. WebGreen plants and algae use light energy to make glucose and oxygen from carbon dioxide and water. Temperature, carbon dioxide concentration and light intensity can affect the rate of photosynthesis.
Webthe light intensity is proportional to distance - it will decrease as the distance away from the bulb increases. The bubbles produced over one minute periods are recorded. The rate of... WebThere are several ways of measuring the rate of photosynthesis in the lab. These include: the rate of oxygen production (number of bubbles or volume of oxygen gas given off in a set time) the...
