Type 4: Cell Surface with Additional Extracellular and Intracellular Material
Both the surface structure of the Cryptophyta and that of the Euglenophyta can be grouped under
this type. The main diagnostic feature of the members of the Cryptophyta is their distinctive kind of
cell surface, colloquially termed Periplast. Examples are Chroomonas (Figure 2.20) and Cryptomo-
