  1. Examination of Microorganisms

  2. 1 Fungi • Unicellular organisms • Can be seen forming colonies • Contain cell walls • Yeasts • 10 – 100 μm • Molds • @ 7 μm • Examples • Penicillium (1) • Aspergillus (2) • Rhizopus (3) • Saccharomyces (Yeast) 2 3 4

  3. Protozoa • Unicellular • @150μm • No cell walls • Trophozoite and cyst forms • Classified by means of locomotion • Examples: • Paramecium • Amoeba

  4. Bacteria • Unicellular • @ 1-5μm in length • Cell wall • 3 shapes: • Cocci • Bacilli • Spirillum

  5. Algae • Most unicellular • Photosynthetic • Examples: • Green algae – 5-10 μm • Volvox – 500 μm
