- DFour
Correct answer
A. Three
Step-by-step solution
Statement A is incorrect because all cells in epithelium are held together with little (not abundant) intercellular material. Statement B is incorrect because adhering junctions (not tight junctions) perform cementing to keep neighbouring cells together. Tight junctions stop substances from leaking across a tissue. Statement C is correct as gap junctions facilitate cell communication by connecting the cytoplasm of adjoining cells. Statement D is incorrect because specialised junctions provide both structural and fu
