• Motile unicellular algae. • Generally oval and/or circular. • Cell wall is made up of a glycoprotein and non-cellulosic polysaccharides instead of cellulose. • Two anteriorly inserted whiplash flagella. Each flagellum originates from a basal granule in the anterior papillate or non-papillate region of the cytoplasm. Each flagellum shows a typical 9+2 arrangement of the component fibrils. WebAccording to their morphology, these mobile unicellular algae, as a rule, are oval in shape. The cell wall consists of a glycoprotein. Chlamydomonads multiply both sexually and asexually.
