Final answer:
Stem cells in a tissue divide to create a continuous supply of differentiated cells, thanks to their capacity for self-renewal and differentiation. They are unique in their potential to regenerate and form specific cells as needed for tissue growth and repair.
Step-by-step explanation:
In a tissue, the cell type that divides to create a continuous supply of differentiated cells is the stem cells. Stem cells have the unique ability to diversify and can continually divide and regenerate new stem cells, which then differentiate into specific types of cells needed by the body. Unlike other cells, stem cells have a vast potential for differentiation and regeneration, which makes them incredibly important for tissue growth and repair.
For example, hematopoietic stem cells in adult bone marrow give rise to red blood cells, white blood cells, and platelets. Similarly, other types of adult stem cells, like mesenchymal stem cells, can differentiate into various types of muscle cells. This capacity of stem cells for self-renewal and differentiation underlines their crucial role in maintaining tissue integrity.
