They also vary in their swimming period. These recipes delineate laboratory methods and reagents, as well as critical steps and pitfalls of the procedures. They are sessile or they float. Thank you for watching! It moves around with cilia. Here, we use beat patterns observed in Paramecium. They bend and straighten. Near the base of their flagella there is a single, large, mitochondrion containing a disc-shaped kinetoplast-a key feature for this clade- which contains a network of mitochondrial DNA. Named for their beautiful spiral chloroplasts, spirogyras are filamentous algae that consist of thin unbranched chains of cylindrical cells.
