or embryo-sac. But these represent in their position in the life- 

 cycle that haploid generation which will be seen later in larger pro- 

 portions and greater independence in such plants as the Ferns and

 gametes to form a zygote, which closes the haploid phase. This event 

 forms the starting point for the new diploid individual, which is the 

 Germ or Embryo.
