  • Pellicle: firm flexible outer covering
  • no cell wall
  • intracellular digestion
  • 2 contractile vacuoles (osmoregulation)
  • macronucleus (large bean) chromosome duplication
  • micronucleus (small) store genetic info
  • asexual (mitosis) and sexual (conjugation)

RO: Micrasterias

A

Phylum: charophyta
-freshwater, unicellular, bilateral symmetry
-motile (glides): secretes mucilage
