Final answer:
Osteoblasts are cells responsible for the formation of new bone tissue. They create and deposit the organic and inorganic components of the bone matrix, which later become mineralized.
Step-by-step explanation:
Cells that produce new bone tissue are called osteoblasts. These cells are responsible for bone formation by synthesizing and secreting the organic and inorganic parts of the extracellular matrix of bone tissue, including collagen fibers. After osteoblasts deposit the bone material into the matrix and become trapped in these secretions, they differentiate into less active osteocytes, which are mature bone cells that maintain the bone's structure. Meanwhile, osteoclasts are involved in the breakdown of bone tissue, essential for bone remodeling and calcium regulation.
