Short Answer Questions

Q6. Define epithelial tissue. List TWO general functions of epithelial tissue in the human body.

Q7. Differentiate between simple epithelium and stratified epithelium. Give one example of each.

Q8. What is the function of cilia in ciliated columnar epithelium? Where is this tissue found?

Q9. Why does stratified squamous epithelium have multiple layers of cells? How does this structure help in its function?

Long Answer Questions

Q10. Describe the structure and function of the following types of epithelial tissue with diagrams and examples:

(a) Squamous epithelium

(b) Cuboidal epithelium

(c) Columnar epithelium

(d) Ciliated epithelium

Q11. Explain how the structure of different types of epithelial tissue is adapted to their specific functions. Give at least THREE examples.


APPLICATION / ANALYSIS

Q12. A person who smokes cigarettes for many years develops a chronic cough and frequent lung infections. Doctors find that the cilia in their respiratory tract are damaged.

(a) What is the normal function of cilia in the respiratory tract?

(b) How does damage to these cilia lead to frequent lung infections?

(c) If the person stops smoking, can the cilia recover? Explain the process.

Q13. During a biology practical, a student examines slides of different tissues under a microscope:

Slide A: Single layer of flat, tile-like cells

Slide B: Single layer of cube-shaped cells

Slide C: Multiple layers of flat cells

Slide D: Tall column-like cells with hair-like projections on top

(a) Identify the type of epithelial tissue in each slide.

(b) Suggest ONE location in the human body where each tissue might be found.

(c) A student argues: "Slide C is the best type of epithelium because it has the most layers." Do you agree? Give reasons.
