Biology Quiz

What is the function of the nucleus in a cell?

• It controls all of the cell's activities.

• It provides support to the cell.

• It contains chlorophyll for photosynthesis.

• It stores solution of sugars and salts.

What should be done before increasing the magnification on a microscope?

• The slide should be removed.

• The area of the slide should be moved to the center of the field of view.

• The microscope should be turned off.

• The objective lens should be changed.

What is the main role of the cell wall in plant cells?

• It controls the entry and exit of materials.

• It is the site of chemical reactions.

• It provides support to the cell.

• It stores genetic information.

How is the total magnification of a microscope determined?

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

• By adding the magnification of the objective lens to the magnification of the eyepiece lens.

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

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