Kinetoplastlda trypanosoma, phylum archaeprotista trlchonympha, and phylum chlorophyta. Surface bound by delicate cell membrane through which materials pass in and out. Has not distinct head or tail end. Creates a cyst during harsh environments or lack of food. Covered by a stiff but flexible outer covering (pellicle) Asexual reproduction/ conjugation (a form of sexual recombination) Causes chagas" disease in south america, and sleeping sickness in africa . Lives as parasites in insects, certain plants & many vertebrates. Large flagellate that lives in the intestine of wood-eating termites.
