These organisms, which include Trachelomonas and Phacus, possess the polysaccharide paramylon in their cytoplasm to store food.
These organisms, which include Trachelomonas and Phacus, possess the polysaccharide paramylon in their cytoplasm to store food. They have a single photosensitive red "eyespot" on their flagellar pocket and their cell surface or pellicle is formed from protein strips arranged helically from their apex to their posterior, allowing for their namesake motion or metaboly. All of them are essentially biflagellate with one visible protruding flagellum. FTP, name these unicellular algae which often contain chlorophyll perhaps acquired from ingesting green algae.
