Question

Cells derived from any of the three germ layers are

• A. Totipotent stem cells
• B. Pluripotent stem cells
• C. Multipotent stem cells
• D. Unipotent stem cells

Hint:

Totipotent → all cells including placenta
Pluripotent → all body cells (3 germ layers)
Multipotent → limited lineages
Unipotent → one cell type

Answer 1

The Correct Option is B

Pluripotent stem cells have the ability to differentiate into any cell type derived from the three primary germ layers: ectoderm, mesoderm, and endoderm. This means they can give rise to nearly all cell types in the body, but not extra-embryonic tissues like the placenta.
- Totipotent stem cells (e.g., zygote) can give rise to all embryonic and extra-embryonic cells.
- Multipotent stem cells can differentiate into a limited range of cells within a specific germ layer.
- Unipotent stem cells can give rise to only one specific cell type.
Thus, the correct answer is pluripotent stem cells.

Answer 2

Step 1: Understand the types of stem cells based on potency
- Totipotent stem cells can form all cell types including extra-embryonic tissues.
- Pluripotent stem cells can form cells from all three germ layers (ectoderm, mesoderm, endoderm) but not extra-embryonic tissues.
- Multipotent stem cells can form a limited range of cell types within a particular lineage.

Step 2: Relate the question to stem cell potency
Cells derived from any of the three germ layers imply the ability to differentiate into multiple cell types from ectoderm, mesoderm, and endoderm.
This characteristic is typical of pluripotent stem cells.

Step 3: Final Conclusion
Therefore, cells derived from any of the three germ layers are pluripotent stem cells.
