Cellular Microscopy Techniques starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Cellular Microscopy Techniques.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11

Describe one advantage and one limitation of using electron microscopy in cell biology.
Describe one reason why oil immersion is used with high-power objective lenses in light microscopy.
Describe the principle of fluorescence microscopy.
Explain the main advantage of confocal microscopy over traditional fluorescence microscopy.
Explain the main difference between transmission electron microscopy (TEM) and scanning electron microscopy (SEM).
A researcher wants to study the arrangement of microtubules in a cell. Which microscopy technique should they use for the best resolution? (1) Bright-field (2) Phase-contrast (3) Transmission electron (4) Scanning electron

Which of the following best describes the function of the objective lens in a compound microscope? (1) Illuminates the specimen (2) Magnifies the image (3) Holds the slide (4) Adjusts the focus
The ________ adjustment knob is used for precise focusing at high magnification.
The ________ is the part of the microscope where you place the slide containing the specimen.
The ability of a microscope to distinguish two close objects as separate is called ________.
The maximum magnification typically achievable with a standard compound light microscope is about ________x.
True or False: Atomic force microscopy can be used to study the surface of biological samples at the nanometer scale.
True or False: Confocal microscopy allows for the collection of sharp, optical sections from thick specimens.
True or False: Electron microscopes use beams of electrons instead of light to visualize specimens.
True or False: Phase-contrast microscopy enhances contrast in unstained, transparent specimens.
