Write the weight in Table 2.8. This is a much more reliable version of the practical than the frequently used Elodea pondweed. ... At the 25cm distance the Elodea had a higher rate of oxygen production (0.0036) compared to the rest of the distances. The purpose of this laboratory activity is to measure the rate of photosynthesis for a plant, Elodea, when it is exposed to different light conditions. In this practical experiment, the rate of photosynthesis is measured by counting the number of bubbles rising from the cut end of a piece of Cabomba pondweed. Photosynthesis-Elodea Lab. Place a small pinch of sodium bicarbonate into a test tube (this increases carbon dioxide in water) Fill the test tube with distilled water so that the stem is completely submersed.
