In ferns,the prothallus (gametophyte) normally produces gametes that fuse to form a zygote,which then develops into a sporophyte. However,in $Apogamy$,the sporophyte arises vegetatively from the cells of the prothallus. $Apospory$ is the opposite process,where a gametophyte develops from a sporophyte without meiosis. $Parthenocarpy$ refers to the development of fruit without fertilization. $Parthenogenesis$ is the development of an embryo from an unfertilized egg.
