Diversity of Microorganisms Protozoa (Sing. Protozoan)  Eucaryotes: “True nucleus”  DNA is surrounded by nuclear membrane.  Cells have membrane bound organelles and are larger than those of procaryotes.  Unicellular  Kingdom Protista  Sexual or asexual reproduction  Classified based on locomotion:  Pseudopods: “False feet”. Cytoplasmic extensions.  Example: Amoeba Diversity of Microorganisms Protozoa (Sing. Protozoan)  Classified based on locomotion:  Flagella: Long whip like appendages.  Example: Trichomonas vaginalis, causes trichominiasis, a sexually transmitted disease.  Cilia: Small hair like appendages  Nonmotile: Do not move in their mature forms.  Example: Plasmodium spp., causative agent of malaria. Protozoa Belong to Kingdom Protista: Eucaryotic Unicellular or Simple Multicellular Organisms Diversity of Microorganisms Algae (Sing. Alga)  Eucaryotes: “True nucleus”  Photosynthetic: Important part of food chain      because produce oxygen and carbohydrates used by animals. Unicellular or multicellular Kingdom Protista Sexual or asexual reproduction Cell walls composed of cellulose Found in aquatic environments (oceans, lakes, rivers), soil, and in association with plants.
