Homework Answers
C) only gap junctions will allow movements of dye from one cell to other cell if dye is injected in to a cell.
Gap junctions are the tube like connections between cell, involve in migration of small molecules between the cell.
While in tight junctions, membrane of cells are attached tightly not allow movements of molecules. These tight junction appear at the places subjected to high stretch.
Similar desmosomes also not allow migration of molecules.
D) based on previous information if dye is added extracellular to animal sheet than only in case of desmosome dye can come to the interior surface of cellular sheet.
As cells are tightly linked in tight junction and in gap junctions would not allow migration of dye from extracellular face to intracellular face.
Only desmosomes allow migration from extracellular to intracellular side.
