Stigonema algae. Light micrograph of filaments of the blue-green algae Stigonema ocellatum. The name "Stigonema" translates from latin:"stigon" meaning "dotted" and "nema" meaning "thread". Here,the thread-like filaments appear dotted with rows of cells. The filaments are enclosed in a gelatinous protective sheath,and growth occurs at the tip of each branching filament. Blue-green algae (group: Cyanophyta) are considered to be one of the most primitive organisms,dating back to pre-Cambrian times. Stigonema is a filamentous blue-green algae found on,among other places,dripping rock surfaces and waterfalls. Magnification: x60 at 35mm size | |
