Which of the following is not found in cartilage but is found in bone?
A
Proteoglycans
B
Chondrocytes
C
Collagen fibers
D
Osteocytes
Verified step by step guidance
1
Understand the basic structure of cartilage and bone. Cartilage is a flexible connective tissue found in various parts of the body, while bone is a rigid organ that constitutes part of the vertebrate skeleton.
Identify the components typically found in cartilage. Cartilage contains chondrocytes, which are the cells responsible for maintaining the cartilage matrix, as well as proteoglycans and collagen fibers, which provide structural support and flexibility.
Identify the components typically found in bone. Bone contains osteocytes, which are mature bone cells that maintain the bone matrix, as well as collagen fibers and mineral deposits that provide strength and rigidity.
Compare the components found in cartilage and bone. Note that both cartilage and bone contain collagen fibers, but only bone contains osteocytes.
Conclude that osteocytes are not found in cartilage but are found in bone, making them the correct answer to the question.
