Answer
The presence of an epiphyseal plate means that bone length may still increase.
Solution
1. The epiphyseal plate (growth plate) is an area of growing cartilage near the ends of the long bones.
2. As long as the epiphyseal plate is present, the bone continues to grow in length due to the process of endochondral ossification.
3. When the epiphyseal plate is replaced by bone (a process known as epiphyseal closure), bone length no longer increases.
4. Therefore, the presence of an epiphyseal plate indicates that the bone length may still increase.

The presence of an epiphyseal plate, also known as the growth plate, is a clear sign that bone length is still increasing. This cartilage structure allows for the continued growth of long bones during childhood and adolescence, acting as a site where new bone tissue is added, thus lengthening the bone. Once the epiphyseal plate fully ossifies and turns into solid bone, also known as the epiphyseal line, it indicates that growth in length has stopped. So if you see an epiphyseal plate, it means the bone is still growing! How cool is that?
