Cartilage is best described as which type of tissue?

• A. Cartilage
• B. Bone
• C. Tendon
• D. Muscle

Answer: (A)

This question tests tissue classification in animals, specifically recognizing cartilage as a type of connective tissue. Cartilage is made up of chondrocytes embedded in a gel-like extracellular matrix rich in collagen and proteoglycans, and it is typically avascular, giving it a firm yet flexible support role in joints, the nose, and ears. This distinguishes it from bone, which is mineralized and highly vascularized and forms rigid structures; from tendons, which are dense regular connective tissues connecting muscle to bone; and from muscle, which is contractile tissue that enables movement. So describing cartilage as a type of connective tissue accurately reflects its structure and function.
