Question
In a developing embryo, analyse the consequences if cell divisions are not followed by cell differentiation.
✓
Answer
During development of an embryo, cell differentiation is necessary to produce different kinds of tissues which could later develop various organs and organ system. If cell differentiation does not happen, then different tissues would not be produced and the embryo would only develop into a mass of identical cells; unable to develop into a new individual. This can be compared with differentiation of meristematic cell in plants. In vascular plants, it is differentiation which ultimately results in formation of specialized tissues which performs various functions.
