- D.
Production of red blood cells
Correct Answer
A. Growth in lengthExplanation
The epiphyseal plate is a cartilaginous growth plate located at the ends of long bones in children and adolescents. It is responsible for longitudinal bone growth, allowing bones to increase in length. As the cartilage cells in the plate divide and mature, new bone tissue is formed, leading to bone growth. Once growth is complete, the epiphyseal plate ossifies and becomes the epiphyseal line. Therefore, the function of the epiphyseal plate is growth in length.Rate this question:
