The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Stem Cells**: Stem cells are specialized cells in the body that have the unique ability to divide and differentiate into various types of cells. They are often referred to as "raw cells" because they can develop into different cell types. 2. **Sources of Stem Cells**: Stem cells can be extracted from several sources in the body and plants. The common sources include: - **Bone Marrow**: This is one of the primary sources of stem cells in adults. Bone marrow contains hematopoietic stem cells, which can develop into various types of blood cells. - **Blood**: Stem cells can also be found in peripheral blood, especially after mobilization from the bone marrow. - **Plant Roots**: In plants, stem cells can be found in the roots, but this is not the primary focus when discussing human stem cells. - **Plant Stems**: While stem cells can be extracted from plant stems, this is less relevant in the context of human stem cells. 3. **Conclusion**: The most significant source of stem cells in humans is the bone marrow. Therefore, the correct answer to the question is that stem cells may be extracted from bone marrow. **Final Answer**: Stem cells may be extracted from bone marrow. ---
