Question

place the appropriate labels in their respective targets.

show instructions

columnar cell, simple epithelium, stratified epithelium, squamous cell, cuboidal cell

Explanation:

Identify tissue layers

Using the Epithelial Tissue Classification knowledge point, we classify epithelial tissues by the number of cell layers. The top-left diagram shows multiple layers of cells stacked on top of each other, which represents a stratified epithelium. The top-right diagram shows a single layer of flat cells, which represents a simple epithelium.

Identify cell shapes

We classify individual epithelial cells by their physical shape:

• The bottom-left cell is cube-shaped with a central, round nucleus, representing a cuboidal cell.
• The bottom-middle cell is tall and column-like with an elongated nucleus, representing a columnar cell.
• The bottom-right cell is flat and scale-like with a flattened nucleus, representing a squamous cell.

Match labels to targets

We align each of the five targets with the correct label from the top options:

• Top-left diagram (multi-layered tissue): "Stratified epithelium"
• Top-right diagram (single-layered tissue): "Simple epithelium"
• Bottom-left cell (cube-shaped): "Cuboidal cell"
• Bottom-middle cell (tall/column-shaped): "Columnar cell"
• Bottom-right cell (flat/scale-shaped): "Squamous cell"

Answer:

• Top-left target (multi-layered tissue): Stratified epithelium
• Top-right target (single-layered tissue): Simple epithelium
• Bottom-left target (cube-shaped cell): Cuboidal cell
• Bottom-middle target (tall cell): Columnar cell
• Bottom-right target (flat cell): Squamous cell
