Substitution of usual sexual reproduction by form of reproduction which does not include syngamy and meiosis is called apomixis. Here embryo is developed by some other tissue like nucellus or integument. As nucellus is diploid tissue ,therefore nucellar embryo is apomictic diploid.

In a type of apomixes known as adventives embryony, embryos develop directly from
1 Nucellus or integument
2 Zygote
3 Synergids or antipodals in embryo sac
4 Accessory embryo sacs in the ovule
Explanation:
Development of embryos directly from sporophytic tissues like nucellus, and integuments is called adventive embryony which is also a type of apomixis. Eg: Citrus

Seed formation without fertilization in flowering plants involves process of
1 Apomixis
2 Sporulation
3 Budding
4 Somatic hybridization
Explanation:
Apomixis is a reproductive process in plants that superficially resembles normal sexual reproduction in which there is no fusion of gametes.
