Chlorophyceae

Viridiophytes: green plants -> UTC Clade

Systematics within the Chlorophyceae have changed substantially as a result of ultrastructural and molecular investigations. The class may be broadly separated into those in which flagella basal bodies are displaced clockwise (CW clade, with one exception) and those in which they are directly opposed (DO; the other orders shown here). A number of orders display the DO characteristic, but their position within the phylogeny are often unresolved. One such group is the Oedogoniales (represented here by Oedogonium and Bulbochaete), which features cell division and life cycles different from all other algae. It has been suggested that the Chlorophyceae could be split into further classes on this basis.
