Is the statement true or false? A pronormoblast belongs to the erythron.

The statement is true. A pronormoblast is indeed a type of cell that belongs to the erythron, which refers to the system of cells involved in red blood cell production. Specifically, pronormoblasts are the earliest recognizable precursors in the erythroid lineage of hematopoiesis. They are large nucleated cells found in the bone marrow and undergo several stages of differentiation before maturing into erythrocytes (red blood cells).

This process is important for the continuous production of red blood cells, which are essential for oxygen transport throughout the body. The stages of erythropoiesis, starting from the pronormoblast stage, include subsequent maturation steps leading to basophilic normoblasts, polychromatophilic normoblasts, and ultimately the reticulocyte before becoming mature erythrocytes.

Recognizing the role of pronormoblasts within the erythron provides insight into the process of erythropoiesis and the significance of these cells in maintaining adequate red cell mass.
