Verified step by step guidance

Understand the concept of polarity in epithelial tissues. Polarity refers to the presence of structural and functional differences between the apical (top) and basal (bottom) surfaces of epithelial cells.

Recognize that epithelial tissues are characterized by having distinct cellular orientations. The apical surface often faces the lumen or external environment, while the basal surface is attached to the basement membrane.

Consider the functional implications of polarity. This property allows epithelial cells to perform specific functions such as absorption, secretion, and protection, depending on their location and orientation.

Evaluate the statement given in the problem: 'Polarity is a property of all normal epithelial tissues.' Given the definition and characteristics of epithelial tissues, assess whether this statement is true or false.

Conclude by determining if the statement aligns with the fundamental characteristics of epithelial tissues, which universally exhibit polarity as part of their normal structure and function.
