Final answer:
True, Epithelial cells have a distinct polarity in terms of transport, with different structures on their basal and apical surfaces to support their selective transport functions.
Step-by-step explanation:
True, epithelial cells indeed exhibit polarity related to transport mechanisms. This polarity refers to the structural and functional differences between the top (apical) and bottom (basal) sides of the cells. The different organelles and membrane-bound proteins are distributed in a polarized manner between these two surfaces, which is crucial for the cells' roles as barriers and in facilitating selective transport. For instance, certain organelles are located on the basal side, which is adjacent to underlying tissues, while extensions like cilia are found on the apical surface, facing the lumen or external environment. This organization is vital for the epithelial cells to carry out their functions effectively, such as absorption, secretion, and protecting the body against pathogens.
