Solution
The correct option is C Tight junctions and gap junctions, respectively Cell junctions connect cells to one another and are often found in the epithelial tissue.
These specialised junctions provide both structural and functional links between its individual cells.
Tight junctions stop substances from leaking across a tissue.
Gap junctions connect the cytoplasm of adjacent cells, for the rapid transfer of ions and molecules and thus facilitate communication between the cells.
