104 Animal Cell Junctions

Which type of cellular junction form a "quilted seal" between cells?

• Tight junctions

• Desmosomes

• Gap Junctions

What is a tight junction?

• When the space between cells are closer together than they normally should be
• A chemical reaction
• A specialized connection of interwoven cellular extensions of adjacent animal cells

A type of inter-cellular connection in which the outermost portions of the two cell membranes have a tight seal together is termed a(n)

• tight junction

• intermediate junction

• gap junction

• desmosome

The membranes of cells are anchored to a non-living membrane.

• gap junctions
• tight junctions
• desmosomes

This junction forms an impermeable barrier between cells producing a zipperlike fastening.  Tissues that serve as barriers have these.

• Desmosomes
• TIght Junctions
• Gap Junctions
• Plasmodesmata

Allows for a direct flow of molecules between adjacent cells for communication and resource sharing.

• Desmosomes
• Tight Junction
• Gap Junction
• plasmodesmata

This junction forms an impermeable barrier between cells producing a zipperlike fastening.  Tissues that serve as barriers have these.

• Desmosomes
• TIght Junctions
• Gap Junctions
• Plasmodesmata

This junction allows communication between two cells with adjoining plasma membrane channels.

• Plasmodesmata

Which type of cell junction prevents adjacent cells from being separated or overstretched?

• Tight junctions
• Gap junctions
• Desmosomes

Which type of cell junction includes adherin proteins?

• Tight junctions
• Gap junctions
• Desmosomes
