Identify the types of cell junctions that help to stop the leakage of the substances across a tissue and facilitate communication with neighbouring cells via rapid transfer of ions and molecules.
  1. Gap junctions and Adhering junctions, respectively.
  2. Tight junctions and Gap junctions, respectively.
  3. Adhering junctions and Tight junctions, respectively.
  4. Adhering junctions and Gap junctions, respectively.

Solution

The neighbouring cells in tissues are held together by three types of intercellular junctions such as tight junction, adhering junction and gap junction.
The tight junction prevents the leakage of substances.
The adhering junction cement and adjoining cells with desmosomes, interdigitation, etc.
The gap junction allows the movement of ions, signals and biomolecules between adjoining cells.
