It is observed during maturation of microspore to pollengrain (male gametophyte)

  • When the microspore is still in the microsporangium, the pollen grain or microspore of angiosperms divides for the first time.
  • During this process, an asymmetric spindle is created.
  • It is created with one pole having converged spindle fibres and the other pole having divergent spindle fibres.
  • Larger vegetative cells and smaller spindle-shaped generative cells result from this division.
