Explanation

  • At first zygote divides and make a basal cell and a terminal cell
  • Then the basal cells divides and make 6 - 10 celled suspensors
  • The uppermost cell of suspensor swells up to form a vesicular cell while the lowest cell of the suspensor is called hypothesis.
  • The terminal embryonic cell divides by transvers and vertical divisions and make 16 celled globular embryo
  • Finally the embryo and cotyledons become larger and curve
