It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. Obtain the Elodea a few days in advance of the lab and enhance growth with an artificial light source to ensure active sprigs. Prepare a wet mount of an Elodea leaf with aquarium water. The null hypothesis for the first experiment is that the different wavelengths will not produce a different effect on … Place a piece of elodea in each test tube or glass. University. In this life science lesson, students experiment to find evidence of photosynthesis in elodea leaves.
