The Integumnet produces the Micropyle which provides a specific locus for successful fertilization.
In other gametophytes the Archegonia may be located in a general region but nothing approaches the specificity of the Micropyle. This helps to avoid multiple fertilizations which deplete the nutrients available for the most successful embryo.
