Which of the following statements is correct about the type of junction and their role in our body?
Adhering junctions facilitate the cells to communicate with each other.
Tight junctions help to stop substances from leaking across a tissue.
Tight junctions help to perform cementing to keep neighbouring cells together.
Gap junctions help to create gap between the cells and tissues.
Solution
The correct answer is option (2), because tight junctions help to stop substances from leaking across a tissue.
Options (1), (3) and (4) are incorrect because
- Adhering junctions perform cementing to keep neighbouring cells together.
- Gap junctions facilitate the cells to communicate with each other by connecting the cytoplasm of adjoining cells for rapid transfer of ions, small molecules and sometimes big molecules.
