• Fungi (singular: fungus)

– Many (such as yeasts and some molds) are single-celled microorganisms

– Some (mushrooms) are multicellular macroscopic organisms

– Have cell nucleus and intracellular structures
– All fungi absorb ready-made nutrients from the environment

• Protozoa

– Single-celled microscopuc organisms with at least one nucleus and numerous

intracellular structures

– Few species of amoebae are visible with the naked eye

– Most protozoa obtain food by engulfing or ingesting smaller microorganisms
