Epithelia serve several essential functions in the body, including absorption, controlling permeability, producing specialized secretions, and providing physical protection. However, they do not play a role in supporting muscle cells.
Explanation: Epithelial tissues form protective layers on body surfaces and line cavities and organs. They are vital for processes like absorption (as in the intestines), secretion (like glands), and regulating what enters and exits the body (permeability). Nonetheless, the support of muscle cells is primarily the role of connective tissues rather than epithelia. Hence, option ‘e’ supporting muscle cells is the correct answer as it does not pertain to the functions of epithelial tissues.
