Like bracelets of brilliant emeralds, the miniature filamentous cellular algal genus Ulothrix glisten under the nourishing sun. Converting carbon dioxide and sunlight into sugars, carbohydrates, stored chemical energy and oxygen is the day job for these freshwater green algae found in clear streams and ponds as well as stagnant pools and watering-troughs. The green filaments that make up the algal masses of Ulothrix are long chains of plant cells with a rounded tip and a holdfast cell at their base. Under a hand-lens or microscope, the green chloroplasts, cell walls and nuclei are visible in their transparent cells.
