Q147 / 200 · NEET 2021 · Zoology
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.
- AGap junctions and Adhering junctions, respectively.
- Correct answerBTight junctions and Gap junctions, respectively.
- CAdhering junctions and Tight junctions, respectively.
- DAdhering 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.
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.
Hence, the correct answer is option: 'B'.
