When observing simple squamous epithelial tissue under a microscope, which of the following best describes its appearance?

• A. A single layer of tall, column-shaped cells
• B. Multiple layers of flat, scale-like cells
• C. A single layer of flat, scale-like cells
• D. Multiple layers of cube-shaped cells

Answer: (C)

Verified step by step guidance

1. Understand the structure and function of simple squamous epithelial tissue: Simple squamous epithelium consists of a single layer of flat, scale-like cells. These cells are thin and allow for efficient diffusion and filtration, making them ideal for areas like the alveoli in the lungs and the lining of blood vessels.
2. Compare the descriptions provided in the options: Analyze each option to determine which matches the characteristics of simple squamous epithelial tissue. For example, tall column-shaped cells describe columnar epithelium, and multiple layers of cells describe stratified epithelium.
3. Focus on the term 'simple' in the name: 'Simple' indicates a single layer of cells, which rules out any options describing multiple layers.
4. Focus on the term 'squamous' in the name: 'Squamous' refers to flat, scale-like cells, which rules out options describing cube-shaped or column-shaped cells.
5. Select the correct description: Based on the analysis, the correct description of simple squamous epithelial tissue is 'A single layer of flat, scale-like cells.'
