Which is not an example of epithelial tissue?

Cartilage

The correct answer is Option (1)- Cartilage

Cartilage is not an example of epithelial tissue.

Explanation:

• Epithelial tissue is one of the four basic types of animal tissues and is characterized by tightly packed cells that form continuous sheets.
• Examples of epithelial tissues include the skin, lining of the digestive tract (intestine), and glandular tissues that produce secretions.
• Cartilage, on the other hand, is a type of connective tissue. It is composed of cells called chondrocytes and a matrix of collagen or elastic fibers embedded in a gel-like substance. Cartilage provides support and flexibility to various structures in the body, such as the nose and ear.
• Glandular tissues, which can be derived from epithelial tissues, are responsible for producing and secreting substances like hormones or enzymes.

In summary, cartilage is not an example of epithelial tissue; it is a type of connective tissue. Epithelial tissues include examples like skin, intestine, and glandular tissues.
