Step 1: Understanding embryo development.
After fertilization, the zygote divides to form two cells: an apical cell and a basal cell.
Step 2: Role of basal cell.
The basal cell divides to form the suspensor, which helps in pushing the embryo into the endosperm and provides nourishment.
Step 3: Role of apical cell.
The apical cell develops into the main body of the embryo.
Step 4: Conclusion.
Therefore, the suspensor develops from the basal cell.
