Cell Processes Review

The cell membrane is permeable to water, oxygen and carbon dioxide but not permeable to salts, polar molecules or large molecules. Because of this the cell membrane is said to be _____.

• selectively permeable

• a phospholipid bilayer

• a fluid mosaic model

• gatekeeping

Passive transport REQUIRES energy for movement of substances from high to low concentrations.

• true

• false

What are the three types of passive transport?

• diffusion, facilitated diffusion, transport protein

• transport protein, osmosis, diffusion

• diffusion, facilitated diffusion, osmosis

• active transport, osmosis, facilitated diffusion

Protists in ponds obtain oxygen from the water around them. Oxygen is in a high concentration outside of the cell and a low concentration inside of the cell. What will happen?

• Oxygen will diffuse into the cell.

• Oxygen will diffuse out of the cell.

• Oxygen will move by active transport into the cell.

• Oxygen will move by osmosis out of the cell.
