Quizplus · Accepted Answer

C - D - A - BAppositional growth of cartilage involves stem cells in the perichondrium undergoing mitosis (C), followed by the differentiation of these cells into chondroblasts (D). These chondroblasts then produce and secrete new matrix (A), and as they become embedded in the matrix, they differentiate into chondrocytes, each within its own lacuna (B).
