Cell Membrane and Transport

How does a cell maintain homeostasis?

• Regulates what enters and leaves the cell
• Flexibility
• Protective barrier
• Structure and support

Another term for equilibrium is...

• Equality
• Babycakes
• Homeostasis
• Balance

What is another term for "selectively permeable"?

• Porous
• Acts like a switch
• Permanent
• Semipermeable

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

• All materials can enter and leave the cell
• Certain things can enter while others cannot
• The cell manually sorts through all materials
• Only certain cells can interact with the cell.

Most of the cell membrane is made of...

• Lipids
• Carbs
• Proteins
• Nucleic acids

How many layers is the lipid bilayer?

• 1
• 2
• 3
• 4

A can of air freshener is sprayed in the opposite side of the room.  Ten minutes later you start to smell the scent.  This is an example of 

• diffusion
• active transport
• endocytosis
• osmosis

The movement of water across a selectively permeable membrane without the use of any energy is called

• endocytosis
• diffusion
• active transport
• osmosis

Two examples of passive transport are

• Earth and Sun
• Diffusion and Osmosis
• Energy and Wind
• None of the above

What a cell needs to transport particles by active transport?

• Sun
• Wind
• Energy
• Channels
