Self-Check: Microorganisms Viruses belong to the Acellular category of microorganisms. Self-Check: Categorizing Organisms Complete the following activity by dragging the organisms to the appropriate category. Self-Check: Microorganism Types Drag and drop to match the terms to the lower three images. Self-Check: Cellular Organization Drag and drop to match the term to the figure. Self-Check: Branches of Microbiology Match the following branches of microbiology to their proper description. Self-Check: Historical Foundations Leeuwenhoek was able to observe living microorganisms under the microscope he constructed in 1674 (except for acellular infectious agents.) Carolus Linnaeus grouped Leeuwenhoek’s findings into six categories. Complete the concept map by dragging and dropping the terms into the correct areas.

Methods in Microbiology Prepare: Methods in Microbiology • In order to identify a microorganism, we must first grow the organism on • The first microscope with magnification of around 300x was invented by this Dutch Tailor • The most common student microscope is the • The purpose of staining is to Self-Check: Methods Used in Microbiology Self-Check: Labeling the Student Light Microscope Identify the four highlighted parts of the microscope by dragging the labels to their correct location. Self-Check: Microscope Lenses Most student microscopes use lenses. Self-Check: Magnification The magnification of the objective lens with a total magnification of 1000X and an ocular magnification of 10X is . Self-Check: Types of Microscopy What type of microscopy would use stains to aid in the observation of these microbes against an illuminated background using visible light? Self-Check: Types of Microscopy II What type of microscopy is used to produce image of the surface of the microbes? Self-Check: Staining is the difference in the light intensity between the background and the object. Self-Check: Isolation of Microorganisms The method involves spreading bacteria across an agar plate with a loop. Self-Check: Biochemical Identification Drag and drop each label to its corresponding definition. Reflect: Methods in Microbiology • refers to the microscope's ability to show two separate objects as discrete and distinct. • Agar is an important component of media because . • Match the following microscope types to the specimen • A microbiologist inoculates Staphylococcus epidermidis and Escherichia coli into a culture medium both of which grow at 37oC. Following incubation, only the E. coli grows because . • Agar is a complex polysaccharide that comes from a/an . • medium distinguishes different types of microorganisms based on an observable change in the colonies or in the medium. • A microbiologist makes a fixed smear of bacterial cells and stains it with methylene blue. All cells appear blue under the oil immersion lens. This is an example of . • Mannitol salt agar is selective for . • The three physical forms of laboratory media are , , and .
