discuss the role of cytoplasm in development
Answers
During this period of time, some regions of the cytoplasm accumulate some of these cytoplasmic determinants, whose distribution is thus very heterogenic. They play a major role in the development of the embryo's organs. Each type of cell is determined by a particular determinant or group of determinants.
Many different types of cells arise from the totipotent egg during embryonic development. Two distinct concepts have been formulated to explain how this diversity of cell types is generated. The first is that the egg already contains regionalized components known as cytoplasmic determinants that influence cell fate as a consequence of their differential segregation into various blastomeres during cleavage. The second is that certain embryonic cells, whose unique properties were established earlier by the action of localized determinants, influence the development of adjacent cells by induction. Thus, the diversification of embryonic cells is thought to be the result of differential gene expression mediated by the combined activity of cytoplasmic determinants and inductive processes
