Cell Membrane Bubble Lab

Why do bubbles make a great stand in for cell membranes?

• fluid

• flexible

• self-repair

• All of the above

Which end of the phospholipid is attracted to water?

• head

• tail

Which end of the phospholipid is repelled by water?

• head

• tail

Cell membranes are static and cannot flex or bend.

• True

• False

Both the bubble layer and the cell membrane can repair small breaks in the bilayer.

• True

• False

Membrane surrounding organelles in Eukaryotic cells feature a phospholipid bilayer like the one found in the outer "plasma" membrane.

• True

• Flase

Some membrane proteins can create a channel or passageway though the membrane for large particles and charged particles.

• True

• False

What are Gap Junctions?

• A gap between two cells where they are not able to connect.

• A passageway between two cells creating a quick way to move materials between the two cells.

• A specialized compartment to store waste materials.

Some single-celled bacteria reproduce by splitting into two. This is known as fusion

• True

• False

Which of the following is NOT a Cell Concept that was shown in the cell membrane bubble lab?

• Membranes can self-repair

• Eukaryotic cells feature membrane bound organelles

• Membranes are tough, rigid and do not allow materials to pass through.

• Gap junctions aid in transport between animal cells

• Many bacteria produce through binary fission
