Solution

Dear student
The process of formation of different tissues, organ and organ system from the same DNA of the cell in an embryo is called cellular differentiation. This process of cellular differentiation is controlled by epigenetics where modification of DNA sequence leads to controlled expression of gene in embryo for the formation of different tissues, organs and organ system.
