a. ribosomes
Osteoblasts are cells that are vital for bone formation. They function by secreting an organic matrix called osteoid which primarily consists of the protein collagen, and calcium-binding proteins that later mineralize to form bone. Ribosomes are the organelles responsible for synthesizing proteins by translating messenger RNA (mRNA) into polypeptide chains. Since collagen and calcium-binding proteins are essential components of the osteoid, and given that they are proteins, osteoblasts rely on ribosomes to produce these crucial elements.
