Vedclass · Answer

(C) The process of forming the three germ layers (ectoderm,mesoderm,and endoderm) from the inner cell mass of the blastocyst is known as gastrulation. This process involves the movement and differentiation of cells,not just simple division. While division (mitosis) occurs,the fundamental mechanism that establishes these distinct layers is cellular differentiation,where cells become specialized to form specific tissues and organs. Therefore,the statement that germ layers are formed by the 'division of the embryo' is scientifically inaccurate; they are formed through the 'differentiation of the embryo'.

The three germ layers—ectoderm,endoderm,and mesoderm—are formed by the division of the embryo. Identify the error in the given statement regarding the process of organogenesis mediated by stem cells.
