WebOne glaring difference between plant cells and cyanobacteria is the cell structure. Plants are eukaryotes, meaning they are multicellular and have membrane-bound organelles; this includes a nucleus that holds their DNA. Cyanobacteria are prokaryotes, meaning they are single-celled and do not have a nucleus (Staley et al., 2007). WebWhat You Do: 1. Fill a sink with water and set the beaker in it. Put some elodea in the beaker and cover it with the funnel. 2. Now submerge the test tube in the water so that there is no air inside it. While holding it under the water, carefully place it over the neck of the funnel. Don’t let its mouth break the surface of the water. 3. high temperature silicone mold making
