Microscopy in Microbiology
Biology ⇒ Microorganisms and Microbiology
Microscopy in Microbiology 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 Microscopy in Microbiology.
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 10
Describe the function of the condenser in a light microscope.
Describe the main difference between a light microscope and an electron microscope.
Describe the main use of a fluorescence microscope in microbiology.
Explain the importance of using cover slips when preparing slides for light microscopy.
A student is using a microscope and the image appears dark even though the lamp is on. Which part should they adjust? (1) Eyepiece (2) Diaphragm (3) Coarse adjustment knob (4) Stage clips
