2. Apogamy: Development of a sporophyte (embryo) from any gametophytic cell other than the egg (e.g., synergids, antipodal cells) without fertilization.
3. Sporophytic budding (or Adventitious embryony): Development of an embryo directly from diploid sporophytic cells (like nucellus or integument) without the formation of gametes or fertilization. If “sporophytic budding” refers to this, then all three processes result in an embryo without fertilization.
