(c) During development zygote, divides into large basal cell, called the suspensor cell and the other termed as ‘terminal cell’ or ‘pro-embryo’. The pro-embryo cell after division develops into ‘epibasal’ at terminal and ‘hypobasal’ near suspensor. The ‘epibasal cells’ or apical octant develops into cotyledons and ‘embryo plumule’ the ‘hypobasal cell’ produce the ‘hypocotyl’. |
