Verified step by step guidance

Step 1: Understand the term 'blast cell.' A blast cell is an immature precursor cell that is actively dividing and responsible for producing specific types of tissue.

Step 2: Recall the anatomy of bone tissue. Bone tissue is primarily formed by osteoblasts, which are specialized cells responsible for synthesizing and secreting the bone matrix (collagen and minerals).

Step 3: Differentiate between the options provided: - Osteoblast: Responsible for bone formation. - Erythroblast: Precursor to red blood cells, not related to bone. - Chondroblast: Responsible for cartilage formation, not bone. - Fibroblast: Produces connective tissue fibers, not bone.

Step 4: Match the correct blast cell to the tissue type. Since the question asks for the primary blast cell for bone, the correct answer is osteoblast.

Step 5: Reinforce the concept by noting that osteoblasts mature into osteocytes, which maintain the bone matrix, highlighting the lifecycle of bone cells.
