MIC 206 ASU Practical Test Questions with
Verified Correct Answers
70% Ethanol
Disinfectant used to clean lab surfaces before and after experiments.
Major Classes of Microorganisms
Virus, Algae, Fungi, Protozoa, Bacteria.
Prokaryotes
Nucleoid, no membrane organelles, binary fission
Eukaryotes
Nucleus, organelles, mitosis/meiosis.
Virus
Non-cellular microbe requiring a host cell for replication; phage infects bacteria. Neither pro
or eukaryotic
Algae
Uni- or multicellular, photosynthetic organisms in fresh and marine water; classified by
pigments, storage, and cell wall. Eukaryotic
Protozoa
Single-celled eukaryotes; animal-like nutrition; locomotion via pseudopodia, cilia, or flagella;
examples = Amoeba, Paramecium, Giardia.
Fungi
,Eukaryotic organisms; may be unicellular or multicellular; decomposers with cell walls;
forms = molds (hyphae, spores) and yeasts (budding).
Molds
Multicellular, have hyphae, reproduce asexually and sexually with spores
Yeasts
Unicellular, reporduce asexually with budding
Bacteria
Prokaryotic organisms in diverse environments; energy from chemical/light; identified by
shape, cell-wall type, and motility
Coccus
Round shaped
Bacillus
Small rods shaped
Spirillum
Spiral shaped
Nucleic Acids
DNA/RNA molecules carrying hereditary information.
Proteins
Macromolecules for structure and function (composed of amino acids).
Carbohydrates
, Sugars ending in -ose (e.g., glucose, lactose) used for energy.
Lipids
Fatty-acid-based molecules forming external phospholipid bilayer.
Nucleoid
Region in bacterial cells containing circular DNA chromosome.
Cytoplasm
80% water solution containing ribosomes and inclusions.
Inner Cell Membrane
Site of ATP synthesis and selective permeability (phospholipid bilayer with proteins).
Cell Wall
Provides rigidity and shape; made of peptides and carbohydrates.
Periplasm
Space between cell membrane and outer membrane (in Gram-negative cells only).
Outer Membrane
Additional barrier found only in Gram-negative bacteria.
Capsule
Slimy protective coating outside cell wall (sometimes present).
Flagella
Long filamentous structures providing motility to bacteria.
Pseudopodia
