Question 1
Slide shows a single layer of flat cells lining a blood vessel.
• Answer: Simple squamous epithelium
• Rationale: Single layer of flattened cells facilitates diffusion.
Question 2
Slide shows cube-shaped cells with large nuclei lining a gland duct.
• Answer: Simple cuboidal epithelium
• Rationale: Cube-shaped cells function in secretion and absorption.
Question 3
Slide shows column-shaped cells with microvilli lining the small intestine.
• Answer: Simple columnar epithelium
• Rationale: Microvilli increase surface area for absorption.
Question 4
Slide shows stratified layers of flat cells in areas of high abrasion (e.g., esophagus).
• Answer: Stratified squamous epithelium
• Rationale: Multiple layers protect against mechanical stress.
