Question

Which of the following tissues is hard but flexible?

• A. Bone
• B. Cartilage
• C. Nerve tissue
• D. Muscle tissue

Answer 1

The correct option is B Cartilage

• Bone cells are embedded in a hard matrix, which is made up of salts of calcium and phosphate. Bone is a hard, rigid, nonflexible structure.
• Nerve tissue contains a cell body from which long, thin hair-like parts arise. So, nerve tissue is a delicate form of tissue, which is involved in signal transmission in the body.
  
• Muscle tissue contains the elongated fibers called muscle fibers. These fibers can contract and relax hence, flexible in nature. But these fibers are not hard.
• Cartilage has widely spaced cells that are interspersed in the matrix made of proteins and sugars. It covers the ends of bones at a joint. It is also present in the ear, nose. Cartilage is a firm, hard tissue, which is softer and more flexible than bone. Therefore, option B is correct.
