Identify the types of cell junctions that help to stop the leakage of the substances across a tissue and facilitation of communication with neighbouring cells via rapid transfer of ions and molecules.

  1. Adhering junctions and Gap junctions, respectively
  2. Gap junctions and Adhering junctions, respectively
  3. Tight junctions and Gap junctions, respectively
  4. Adhering junctions and Tight junctions respectively

Answer

(3) Tight junctions and Gap junctions, respectively

Solution

As per NCERT, cell junctions in epithelium and other tissues are of three types:

⇒ Tight junctions help to stop substances from leaking across a tissue.

⇒ Adhering junctions perform cementing to keep neighbouring cells together.

⇒ Gap junctions facilitate communication between cells by connecting the cytoplasm of adjoining cells, for rapid transfer of ions, small molecules and sometimes big molecules.

∴ Tight junctions and Gap junctions, respectively.
