If the angiosperm gametophyte generation has been reduced to so few cells, why hasn't it been eliminated from the life cycle?

 

The gametophyte generation produces both the protective seed coat and nourishment for developing embryo

 
22. 

Which of the following is a key difference between seedless vascular plants and plants with seeds?
