Quizplus · Accepted Answer

Tight junctions are necessary for creating a barrier between cells because they prevent substances from passing through the spaces between cells. Adhesion junctions and gap junctions allow for communication and adherence between cells, but do not form a tight barrier. Channel junctions are also known as gap junctions and allow for small molecules and ions to pass between cells, so they do not form an effective barrier. Free junctions are not a known type of cell junction.
