cell determination is closely linked to the position of the cells in the embryo. if the cells are surgically involved from the embryo and grown on, they will sitll produce the predetermined cell type as cell differentioation takes place to form tissue and organs, diffrent types of cell produce more an more proteins specific to their celll type
terminal cell : provide polarity to the embryo and embryo develops here.. (apical cell) basal cell : develops suspensor which anchors embryo to the endosperm and serve as a nutrient producer.
Differentiation is important during embryonic development as that is the timeframe for specialization. Differentiation allows for neurons, blood cells, skin and muscle cells organize into tissues, then organs, and ultimately into systems.
