• Stage clips

• Base

Explain how the structure of the cell membrane contributes to its function.

• The rigid structure provides support and protection.

• The lipid bilayer allows selective permeability.

• The thick wall prevents all substances from entering.

• The solid surface allows for easy transport of materials.

Which part of the microscope is responsible for adjusting the amount of light that reaches the specimen?

• Objective lens

• Diaphragm

• Stage

• Arm

Describe the role of proteins in the cell membrane.

• They provide energy for the cell.

• They act as channels and receptors for molecules.

• They store genetic information.

• They synthesize lipids.

What is the function of the eyepiece in a microscope?

• To illuminate the specimen

• To magnify the image formed by the objective lens

• To hold the slide in place

• To adjust the focus

How does the cell membrane maintain homeostasis within the cell?

• By producing energy

• By regulating the entry and exit of substances

• By storing nutrients

• By synthesizing proteins

Which part of the microscope supports the slide being viewed?

• Arm

• Base

• Stage

• Objective lens
