Question
Biology Question on Animal Tissues
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.
A
Gap junctions and Adhering junctions, respectively.
B
Tight junctions and Gap junctions, respectively.
C
Adhering junctions and Tight junctions, respectively.
D
Adhering junctions and Gap junctions, respectively.
Answer
Tight junctions and Gap junctions, respectively.
Explanation
Solution
Tight junctions help to stop substances from leaking across a tissue. 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.
