As you know, simply microbiology is the branch of science that deals with the study of microorganisms ( bacteria, virus, fungi, parasites), and those are non-observable with the naked eye, therefore need of laboratory equipment called microscope to view them.
This Microbiology MCQ is an epicenter for all types of examinations as well as boost your knowledge. There are multiple-choice questions (MCQs). A question with four choices among them one right answer you have to chose. Your score will display after completion of all questions given in a quiz.
So, let’s go to crack the quiz.
Best of luck!
Have a precious day!
Question #1: Which of the following stains is used to classify microorganisms based on their cell wall content?
Capsular stain
Gram stain
Spore stain
Methylene blue
Question #2: Best one about Phase Contrast microscopy
Uses special lenses to distinguish between solid and liquid phases of the cell
Uses special lenses to change the color of light passing through them
Continuously changes the phase of the incident light from the condenser to improve contrast in the specimen
Uses circular filters in the condenser and objective to give contrast to parts of the cell with different refractive indices
Question #3: The transmission electron microscope has the greatest resolving power because it uses an electron beam to view the sample instead of a light beam. The electron beam is used because:
Electrons have longer wavelengths than light waves
Electrons have shorter wavelengths than light waves
Electrons do not penetrate the sample
Light waves are less visible
Electrons are less invasive
