Microscopes usually have several The Florida Elodea is deemed restricted and grows rapidly. This Elodea is also considered an invader as it can crowd other aquatic plant species. Though Elodea provides oxygen and sustenance to aquatic life, they are quite hardy. These aquatic plants reproduce through fragments, meaning that the broken pieces of the plant become new plants. These sugars can then be converted into other sugars, fats, and oils, and stored in other parenchyma cells within the stems and roots. Parenchyma Cells. What evidence did you observe to support your answers? What do you see? when the cork cells reach maturity and are dead they are only being used for structure, not any activity. 1 (1803), p. 20.
