2.5B: Explain the Importance of Cell Differentiation in the Development of Specialised Cells

CELL DIFFERENTIATION: Process involving the development of newly formed cells into more specialised and distinct cells as they mature

IMPORTANCE OF CELL DIFFERENTIATION: All specialised cells and organs constructed from them have developed as a result of cell differentiation Undifferentiated cells receive signals which stimulates the expression of genes for cell to undergo change in metabolism and shape, enabling them to carry out specialised functions - forming a specialised cell Therefore, this allows organism to develop cells necessary to grow and develop as specialised cells can undertake specific functions For example, stem cells can differentiate into nerve cells to carry electrical impulses, hence allowing muscle movement
