Answer:
Correct Answer: B
Solution:
Though the extracellular materials have different functions, they have an important role in the separation of cells.
Extracellular matrix acts as the medium in which cells can remain separated.
When in a certain type of tissue cells are not at all separated, a special structure is formed to hold together the cells, this structure is called cell junction.
This may be formed by the inclusion of the cell in a common matrix.
