Ulothrix filamentous green algae, darkfield photomicrograph
Ulothrix is a genus of filamentous green algae, generally found in fresh and marine water. Its cells are normally as broad as they are long, and they thrive in the low temperatures of spring and winter. They become attached to surfaces by a modified holdfast cell. Reproduction is normally vegetative. They are Eukaryotic and unicellular. They are one of the 5 classes of microorganisms. The plant body consists of unbranched, uniseriate filaments. The cells of the filaments are arranged end to end. They are barrel-shaped or cylindrical in shape.[2] The apical cell is somewhat rounded at its terminal end whereas the basal cell is elongated. It is also called the basal holdfast, which attaches the filament to the cell wall is composed of propectin and cellulose and it lacks mucilage. Each cell has a single girdle-like and parietal chloroplast and two to many pyrenoids are present in each chloroplast
