General Characteristics
  • eukaryotic cells contain membrane-bound nuclei
    and other membrane-bound organelles
  • can have unicellular, colonial and multicellular
    forms
  • important role at the bottom of the food chain
  • reproduce via binary fission
  • level of organization protoplasmic
  • all functions of life are performed within
  • the limits of a single plasma membrane

4
Autotrophic v. Heterotrophic
  • autotrophic converts inorganic compounds into
    an organic,
  • usable form through
  • photosynthetic processes
  • Ex. Volvox, Euglena
  • heterotrophic ingest large food particles and
    digest them intracellularly
  • Ex. Amebas, Paramecium
