Microscope

Why are microscopes generally necessary to observe protists?

• Protists are multicellular organisms that are too large to see with the naked eye.

• Protists are typically very small, unicellular organisms.

• Protists are transparent and cannot be seen without special lighting.

• Protists move too quickly to be observed without magnification.

What is the primary difference between magnification and resolution in microscopy?

• Magnification makes an image appear larger, while resolution is the ability to distinguish between two objects.

• Magnification refers to the clarity of an image, while resolution refers to its size.

• Magnification is only relevant for light microscopes, while resolution is for electron microscopes.

• Magnification is the ability to distinguish between two objects, while resolution makes an image appear larger.

How does a darkfield light microscope differ from a brightfield light microscope in terms of image appearance?

• A darkfield microscope produces a darker image on a light background, while a brightfield produces a light image on a dark background.

• A darkfield microscope produces a light image on a dark background, while a brightfield produces a darker image on a light background.

• Darkfield microscopes use electron beams, while brightfield microscopes use light.

• Darkfield microscopes are used for internal structures, while brightfield microscopes are for surface details.

Which type of electron microscope is best suited for visualizing the internal structures of a specimen?

• Scanning Electron Microscope (SEM)

• Transmission Electron Microscope (TEM)

• Brightfield Light Microscope

• Darkfield Light Microscope

How is the total magnification of a microscope determined?

• By adding the eyepiece lens magnification and the objective lens magnification.

• By subtracting the objective lens magnification from the eyepiece lens magnification.

• By multiplying the eyepiece lens magnification by the objective lens magnification.

• By dividing the objective lens magnification by the eyepiece lens magnification.

Which focusing knob on a microscope is used for making small, precise adjustments to the focus?

• Coarse Focus knob

• Fine Focus knob

• Stage knobs

• Light intensity knob

What is the primary function of the stage knobs on a microscope?

• To adjust the overall brightness of the light source.

• To move the stage vertically for focusing.

• To move the stage horizontally to scan the slide.

• To change the objective lens magnification.

What is the recommended way to carry a microscope?

• With both hands gripping the eyepiece lenses.

• By holding it with one hand on the arm and the other supporting the base.

• By sliding it across the table to its new location.

• With one hand on the stage and the other on the coarse focus knob.
