A)They have polarity.
B)They have a long life span.
C)low rates of mitosis and cytokinesis
D)The cells are loosely packed.

Question

Quizplus · Accepted Answer

Epithelial tissues have polarity, meaning they have distinct apical (upper) and basal (lower) surfaces with different structures and functions, which is important for their functions such as absorption, secretion, and protection.

Answer: C 
 While some epithelial cells can be long-lived, such as the cells lining the gut, they also have a relatively high rate of turnover and renewal through mitosis and cytokinesis, which is important for maintenance and repair of the tissue.

Answer: D 
 Epithelial cells are tightly packed together with little extracellular matrix, which is important for their functions such as forming barriers and maintaining selective permeability. Loose packing of cells would compromise the barrier function and lead to leakage.
