Red blood cells are formed from which cell type?Multiple ChoiceLymphoid stem cellsMegakaryoblastsMyeloblastsHematopoietic stem cells

Breaking Down the Problem

1. Identify the correct cell type responsible for the formation of red blood cells.
2. Understand the roles of each of the provided options in the context of hematopoiesis (the formation of blood cells).

Relevant Concepts

1. Hematopoietic Stem Cells: These are the progenitor cells in the bone marrow responsible for differentiating into various blood cells, including red blood cells (erythrocytes), white blood cells, and platelets.
2. Lymphoid Stem Cells: These are specialized cells that primarily give rise to lymphocytes, a type of white blood cell involved in immune response.
3. Megakaryoblasts: These cells are precursors to platelets (thrombocytes) and do not contribute to red blood cell formation.
4. Myeloblasts: These are precursors to granulocytes, a type of white blood cell, and don't form red blood cells.

Analysis and Detail

• Option Analysis:
  • Lymphoid stem cells: Not correct; they form lymphocytes.
  • Megakaryoblasts: Not correct; they form platelets.
  • Myeloblasts: Not correct; they form granulocytes.
  • Hematopoietic stem cells: Correct; they are responsible for forming all types of blood cells, including red blood cells.

Verify and Summarize

Upon evaluating the roles of each cell type, it is clear that the only cell type responsible for the formation of red blood cells is hematopoietic stem cells.

Final Answer

Hematopoietic stem cells.
