WebAug 14, 2024 · Differentiation. The broad view in biology is that an organism starts as an undifferentiated (unspecialized) cell (the fertilized egg). As development proceeds, individual cells become progressively more differentiated (specialized). Differentiation is usually thought to be primarily unidirectional, especially in higher organisms. WebThe process of differentiation Differentiation from visibly undifferentiated precursor cells occurs during embryonic development, during metamorphosis of larval forms, and following the separation of parts in asexual reproduction. It also takes place in adult organisms during the renewal of tissues and the regeneration of missing parts.
