Question

NEED ANSWER ASAP. As children grow older, their bones grow too. The growth of the long bones happens in a plate near the end of each bone. What happens to the cells of cartilage in a growth plate?
a.Cartilage cells are replaced by bone cells.

b.Cartilage cells lengthen to help stretch out the bone.

c.Cartilage cells expand and become spongy bone cells.

d.Cartilage cells move into spongy bone as bone marrow.

Answer 1

The correct answer is "cartilage cells are replaced by bone cells".

The plate near the end of long bones is called the epiphyseal plate and is composed of cartilage in children. Cartilage and cartilage cells are capable of dividing and adding cartilage matrix which contributes to the lengthening of the bone; then this cartilage will slowly be replaced by bone through aging and hormonal factors.
