Quizplus · Accepted Answer

The extracellular matrix (ECM) of animal cells serves multiple functions such as holding cells together, providing structural support, and imparting mechanical strength. It contains diverse types of macromolecules such as collagen, proteoglycans, and glycoproteins. These molecules also participate in chemical signaling between cells, providing cues for cell migration, differentiation, and proliferation. Therefore, all the options (A, B, C, and D) mentioned in the question are correct, making E the best choice.
