Among the Chlorophyta there are five types of organization: Motile unicellular and colonial organisms, nonmotile unicellular and colonial organisms, filamentous organisms, membranous organisms, and coenocytic and tubular organisms (Bold et al., 1987).
According to Van Den Hoek (1995), additional major characteristics of the Chlorophyta are a flagella that lack tubular hairs, a set of accessory pigments, pyreniods embedded within the chloroplasts, and circular molecules of chloroplast DNA concentrated in areas throughout the chloroplasts.
