In earlier classification schemes, it was placed under plantae in sub category algae and the sole reason of it would be presence of cell wall in both. But in latest schemes of classification as of whittaker which hosted other features apart from gross morphology like cell structure and mainly phylogeny, from which chlamydomonas were placed in a kingdom especially meant for unicellular eukaryotes Protista. For now, Chlamydomonas is a member of protista.
