Answer

Brief Explanations:

Tight junctions form impermeable barriers between epithelial cells. Gap junctions are formed by joined plasma - membrane channels allowing ions and small molecules to pass. Desmosomes hold cells together with extracellular filaments attached to cytoplasmic plaques.

Answer:

  1. tight junction
  2. gap junction; ions
  3. desmosome; extracellular filaments
