These are under alveolates and are characterized by cells that are reinforced by cellulose plates. Chromalveolates that live along the rocky shores of the north temperate zones are able to withstand pounding tides and drying because of their holdfasts and mucilaginous cell walls. Some also feed on nonliving organic matter (detritus). Kingdom: Protista or Protoctista The reason biologists believe that green algae and land plants, both members of the supergroup Archaeplastida, are related is because both of them possess chlorophyll a & b as well as cell walls made of starch.
