PRACTICE EXAMINATION 2026 QUESTIONS
WITH ANSWERS GRADED A+
• Longer wavelengths.
Answer: Lower frequency
• Archae.
Answer: Unicellular, psuedopeptidoglycan cell wall, live in extreme
environments
• fimbriae and pili.
Answer: appendages that provide attachment points or channels
• Mycoplasmas.
Answer: lack of cell walls sterols in plamsa membrane smallest living cell
causes walking pneumonia can't use penicillin
• Staining specimens: Fixed Mount (smear).
Answer: Good for staining
• Scanning electron microscope.
Answer: Electrons are bounced off specimen with costing, surfaces are
easily observed
• Resolution.
Answer: Ability to tell that 2 separate points/objects are separate
• Acid Fast Stain.
Answer: diagnostic tool for detection of mycolic acid and mycobacterium
spp.
• Chlamydia.
Answer: obligate intracellular parasite #1 sexually transmitted disease in US
and it can be symptomatic in women Causes Trachoma-- causes blindness
,• Microbiology.
Answer: the study of organisms too small to be seen with the naked eye
• virology.
Answer: study of viruses
• Pilus (pili).
Answer: - Sex pili are used for conjugation in certain species Conjugation:
the process of using the poli as a bridge to move the DNA between two cells
• what are the different magnifications of a bright field microscope.
Answer: 4x 10x 40x 100x
• Archaea cell membrane.
Answer: some have one layer and others have bilayer, use different
phospholipids that have branching fatty acids and different covalent bonds,
ether linkages, not ester
• Chloroplast function.
Answer: Converts solar energy into glucose (food) in plants
• Endospore Stain.
Answer: identifies cells that have produced endospores
• what kind of microscope do you use when you are working with
microorganisms you can't see?.
Answer: bright field microscope
• Mycology.
Answer: study of fungi
• Bacterial common shapes: Coccus.
Answer: Spherical
• protozoology.
Answer: study of protozoa
• Higher frequency waves have.
Answer: Higher energy (photons move faster)
, • Factors affecting resolution.
Answer: Wavelengths and numerical aperture (ability to gather light by lens)
• Differential Interference Contrast Microscopy.
Answer: similar to phase-contrast but uses two beams of light
• Carboxysomes are.
Answer: carbon fixation inclusions
• systematics.
Answer: the study of the evolutionary history of orgnaims
• Normal Microbiota.
Answer: prevent growth of pathogens produce growth factors such as
Vitamin B and K resistance factors include: skin, stomach acid, and
antimicrobial chemicals
• Eurkarya.
Answer: -animals -Plants - Fungi: • Distinct nucleus • Chitin in cell walls •
Absorb organic chemicals for energy • Yeasts: unicellular • Molds and
Mushrooms: multicellular
• Helminths.
Answer: Eukaryotic, no cell wall, no photosynthesis, multicellular parasitic
worms, microscopic eggs and larvae
• Lysosomes.
Answer: Uses chemicals to break down food and worn out cell parts
• Eukaryotic cell shapes.
Answer: Can vary from spherical, cuboidal, fat, etc
• Cell Theory: Tenant #1.
Answer: Robert Hooke coined the term "cells", Matthias Schleiden observed
plant tissue, Theodore Schwann compared plant and animal
• Cytoskeleton.
Answer: A network of fibers that holds the cell together, helps the cell to
