Dear student,
 
 
 
This type of embryo sac develops from the chalazal megaspore. Its nucleus divides thrice to form eight nuclei. This type is generally referred to as normal type of embryo sac. It is also called polygonum type as it was first time described in polygonum divaricatum by Starsburger.
