WebAquatic plants can be used to demonstrate oxygen evolution in the process of photosynthesis. In theory, when an aquatic plant is placed in a solution containing a source of carbon dioxide (CO 2), in the presence of light of appropriate intensity, the plant will photosynthesise and produce bubbles of oxygen-containing gas. These bubbles can be ... WebJul 10, 2024 · To measure the rate of photosynthesis, place a sprig of elodea in a test tube next to a light source and calculate the number of air bubbles coming out of the plant. …

They use this technique to …
WebOne technique for measuring photosynthesis rate is through measuring oxygen production. Oxygen can be measured by counting pondweed bubbles or by using the Audus apparatus to measure the amount of gas evolved over time. When placed closer to a light source, the rate of bubbling increases, and as the pondweed is moved away from the light source ... Web1. 1. Allow the system to stand 7-10 minutes, or until bubbles begin to appear regularly. Count the bubbles produced each minute for a 5-minute period and average them. Record …
