Detailed explanation-1: -The development of specialized cell types is called differentiation (Table 3.2). These overt changes in cellular biochemistry and function are preceded by a process involving the commitment of the cell to a certain fate.
Detailed explanation-2: -The first mechanism of commitment involves the cytoplasmic segregation of determinative molecules ( cytoplasmic determinants ) during embryonic cleavage, where in the cleavage planes separate qualitatively different regions of the zygote cytoplasm into different daughter cells .
Detailed explanation-3: -Cell determination is influenced by the action of the extracellular environment and the contents of the cell’s genome. When a cell is said to be determined it means that the cell is irreversibly committed to a specific cell fate. See also: morphogenesis, induction, evocator. Last updated on June 24th, 2021.
