Verified step by step guidance

Understand the structure and function of cartilage: Cartilage is a type of connective tissue that provides support and flexibility to various parts of the body. It is avascular, meaning it lacks blood vessels, and relies on diffusion for nutrient and waste exchange.

Review the role of the extracellular matrix in cartilage: The extracellular matrix in cartilage is composed of a gel-like substance containing proteoglycans, water, and collagen fibers. This matrix is flexible and provides the necessary environment for chondrocytes (cartilage cells) to divide and grow.

Analyze the options provided: Evaluate each characteristic mentioned in the problem. For example, cartilage is not highly vascularized, as it lacks blood vessels. It does not lack an extracellular matrix; instead, the matrix is essential for its function. While collagen fibers are present, they are not the sole component of the matrix.

Focus on the correct characteristic: The flexible matrix of cartilage allows chondrocytes to undergo mitosis and expand within the tissue. This flexibility is crucial for cartilage growth and repair.

Conclude why the correct answer is 'It has a flexible matrix': The flexibility of the matrix accommodates cellular division and growth, making it the defining characteristic that supports mitosis of chondrocytes.
