Final answer:
Chondrocytes secrete a matrix that forms cartilage tissue, a firm but flexible type of supportive connective tissue. Unlike bone, which is a dense, hard connective tissue and highly vascularized, cartilage lacks blood vessels in its matrix.
Step-by-step explanation:
Chondrocytes secrete a firm but flexible matrix to form cartilage tissue. These cells are located in spaces called lacunae within the tissue. Cartilage is a type of supportive connective tissue that provides flexibility and smooth surfaces for the movements of the body.
It is distinguished from other types of connective tissue, such as bone tissue, which is a dense, hard connective tissue that makes up the skeletal system. Unlike bone, cartilage does not contain blood vessels within its matrix. Answer to the given question: Chondrocytes secrete a firm but flexible matrix to form d) Cartilage tissue.
Furthermore, when describing bone tissue, it is correctly identified as d) dense, hard connective tissue. Bone tissue, in comparison to cartilage, has a rigid, mineralized matrix containing calcium salts and is highly vascularized, allowing it to quickly recover from injuries.
