Biology Question on Structural Organisation of Animals and plants
Formation of cartilage bones involves
A
deposition of bony matter by osteoblasts and resorption by chondroclasts
B
deposition of bony matter by osteoclasts
C
deposition of bony matter by osteoclasts only
D
deposition of bony matter by osteoblasts only.
Answer
deposition of bony matter by osteoblasts and resorption by chondroclasts
Explanation
Solution
Bone is an unusual tissue in that it is continually being reconstructed. The osteoblasts secrete bone matrix, whereas the large, much branched, motile, lysosome-rich, multinucleate cells, called osteoclasts, destroy bone matrix. The twin process of resorption and resconstruction enables a particular bone to remodel its structure to meet any change in the mechanical requirements of the animal during its development.
