Female Gametophyte


Pictured above is the female gametophyte.  The cells appear larger than the male cells, and fewer of them.  The female gametophyte produces eggs.  To attract the male sperm, the female gametophyte releases a pheromone.  The sperm follows the pheromone concentration gradient to locate the egg.  Once fertilized, the developing sporophyte grows atop the female gametophyte, until it overtakes it.
