Multiple Choice

You look at a slide under the microscope & the tissue has a double layer of cells next to an open surface. The indicated cells are tall and narrow. How would you identify these cells?

Stratified columnar epithelium.

Stratified cuboidal epithelium.

Simple columnar epithelium.

Stratified squamous epithelium.

Verified step by step guidance

Begin by understanding the basic characteristics of epithelial tissues. Epithelial tissues are classified based on the number of cell layers and the shape of the cells. The main types are simple (single layer) and stratified (multiple layers).

Examine the description provided: a double layer of cells next to an open surface. This indicates that the tissue is stratified, meaning it has more than one layer of cells.

Consider the shape of the cells described: tall and narrow. This suggests that the cells are columnar in shape, as columnar cells are typically taller than they are wide.

Match the characteristics observed under the microscope with the options given. The tissue is stratified (multiple layers) and columnar (tall and narrow cells), which corresponds to stratified columnar epithelium.

Review the other options to ensure the correct identification: Stratified cuboidal epithelium consists of cube-shaped cells, simple columnar epithelium is a single layer of columnar cells, and stratified squamous epithelium consists of flat cells. None of these match the description of tall, narrow cells in a double layer.
