Answer:
[D]. None of the above
Explanation:
Epithelium are one of the type of four tissues found in living systems. They possess a variety of functions and are found to line/cover the surfaces of most organs. Epithelial tissues are classified based on the number of cell layers (simple and stratified) and shape (squamous, columnar, and cuboidal).
Based on their shape;
- Squamous epithelium are made up of scale-like flat cells that line the surfaces of alveoli of the lungs etc. They are of thin, flat, irregular shaped cells which fit together like floor tiles to form a compact tissue as stated in this question.
- Cuboidal epithelium contains cells whose shape are similar to that of a cuboid i.e. close width and height. They are located in the kidney tubules, thyroid vesicles and in glands like pancreas.
- Columnar epithelium are relatively thin and elongated in shape, hence, they are found in organs and surfaces whose function mainly is absorption and secretion.
Hence, NONE of the mentioned statements are UNTRUE
