Prothallus (gametophyte) gives rise to fern plant (sporophyte) without fertilization. It is
1 Apospory
2 Apogamy

The formation of gametophyte, from sporophyte, without spore formation or without meiosis is known as:
1 apospory
2 apogamy
3 parthenogenesis
4 none of these
Explanation:
The formation of gametophyte, from sporophyte without spore formation or without meiosis is known as apospory. Apogamy is the formation of sporophyte from the gametophyte without the formation of the gametes. Parthenogenesis is a process of formation of embryo from an unfertilized egg without gamete formation.
