Final answer:
The correct order of steps in the development of red blood cells is as follows: stem cells differentiate into proerythroblasts, which mature into basophilic erythroblasts, then polychromatophilic erythroblasts, then orthochromic erythroblasts. Finally, orthochromic erythroblasts become reticulocytes, which mature into fully functional red blood cells.
Step-by-step explanation:
The correct order of steps in the development of red blood cells is as follows:
- Stem cells in the bone marrow divide and differentiate into proerythroblasts.
- Proerythroblasts develop into basophilic erythroblasts.
- Basophilic erythroblasts mature into polychromatophilic erythroblasts.
- Polychromatophilic erythroblasts develop into orthochromic erythroblasts.
- Orthochromic erythroblasts eject their nuclei and become reticulocytes.
- Reticulocytes mature into fully functional red blood cells.
Each step in the process involves specific changes in the structure and function of the developing red blood cells.
