It is attached to the rocks or other substratum.
Cell Structure of Polysiphonia: The cells have thick wall, differentiated into outer pectic and inner cellulosic layers. The cells are uninucleate with many discoid chromatophores without pyrenoids. Neighbouring cells are connected by pit connections. The cells contain large central vacuole.

one of the cell and is used for locomotion. The other vibrates within a groove in the cell wall running around the cell's middle. The Euglenophyta - or "euglenoids" are interesting organisms that straddle the traditional plant/animal boundary. Some euglenoids are free-living heterotrophic "protozoans" whereas others are photosynthetic green
