Cell Membrane & Passive Transport Review

All of the following describe the cell membrane EXCEPT

• composed of phospholipid bilayer

• site of cellular transport

• regulates what gets into and out of the cell

• site of ATP (energy) production

The passage of a substance from a region of higher concentration to lower concentration is known as

• Homeostasis

• Diffusion

• Active Transport

• Phagocytosis

The yellow and brown portion of this image is:

• phospholipid

• carbohydrate

• chloesterol

• protein

If saltwater plants are placed into a container of distilled water, what effect will this have on the plants?

• The cells will seperate

• The cells will shrink

• The cells will swell

• The cells will remain the same

Facilitated diffusion uses the help of ___________ to move larger or charged molecules from a high to low concentration.

• energy

• cells

• carbohydrates

• proteins

Examples of particles that can diffuse across through the phospholipid bilayer include

• oxygen and carbon dioxide

• sugar

• calcium ions

• water

The cell membrane is selectively permeable, which means...

• All materials can enter and leave the cell

• The cell allows all materials into the cell, but no materials allowed out

• Certain materials can enter easily while others cannot

• The cell allows no materials to enter the cell
