(d) : Nucellar embryo is apomictic diploid. Substitution of usual sexual reproduction by a form of reproduction which does not include meiosis and syngamy is called apomixis. In this process, embryo is developed by some other tissue without fertilisation e.g., nucellus or integuments or infertilised egg. Nucellus is a diploid tissue so nucellar embryo is apomictic diploid.
