What is a characteristic of epithelial cells?
Correct answer
A
Rationale
Epithelial cells are polarized, meaning they have distinct apical and basal surfaces with different functions. This polarity is important for their specialized roles in absorption, secretion, and protection. Therefore, the correct answer is A: 'Polarized.' Choices B and C are incorrect as epithelial cells are not neutral and are not necessarily larger than other cells. Choice D is incorrect as epithelial cells do have specific characteristics.
