(The manager should have two different team members state a tissue and describe its structure). 5. Compare pseudostratified columnar epithelium and simple columnar epithelium and answer the following questions: a) How are these two tissues the same? b) What differentiates pseudostratified columnar epithelium from simple columnar? 6. The bottom (basal) layer of stratified epithelial tissue may have different cell shapes from the top (apical) layer. Which layer determines the shape classification of the tissue?
