Which type of tissue is composed of cells known as chondrocytes, collagen, or yellow elastic fibers?

The correct choice is based on the characteristics and composition of cartilage tissue. Cartilage is a specialized connective tissue that is primarily made up of chondrocytes, which are the cells that maintain cartilage. These cells are embedded in a matrix that contains collagen fibers and may also include elastic fibers, depending on the type of cartilage.

The presence of chondrocytes is a defining feature of cartilage, as they are responsible for producing and maintaining the extracellular matrix. Collagen provides strength and support, while elastic fibers contribute to the flexibility of certain types of cartilage, such as elastic cartilage found in structures like the ear.

In contrast, bone tissue is characterized by osteocytes and a mineralized matrix, muscle consists of muscle fibers that enable contraction, and nerve tissue is composed of neurons and supporting glial cells. These distinct cell types and matrix compositions differentiate cartilage from the other tissue types listed.
