उत्तर
Citrus, Opuntia, and Mango are classic examples of plants exhibiting adventive (nucellar) polyembryony, where diploid cells of the nucellus develop directly into embryos bypassing fertilisation. These plants are commercially important, and this type of polyembryony is utilized in horticulture for asexual propagation.
