Question

Quizplus · Accepted Answer

Tight junctions create a tight seal between epithelial cells by fusing the cell membranes together, preventing the passage of molecules and bacteria between the cells. Anchoring junctions provide structural support and connect adjacent cells, but do not prevent the passage of molecules. Gap junctions and plasmodesmata are found in plant and animal cells, respectively, and allow for communication and exchange of molecules between cells.
