Retaining the zygote on the living gametophyte of land plants  allows it to be nourished by the parent plant

Zygote is the product of fertilization of two gametes. It is the first cell of an organism that divides and redivides to give rise to an entire organism. Thus, protection and nourishment of the zygote becomes the prime aim of the parent organisms.

The land plants usually retain their zygote within the female gametophyte, so that the zygote remains protected and can be nourished till it reaches a suitable condition to germinate.
