When embryo develops from nucellus, it is known as
A) Recurrent agamospermy
B) Adventive polyembryony (sporophytic budding)
C) Non-recurrent agamospermy
D) None of the above

Hint: The zygote first forms a solid ball of cells. The blastocyst is then created, which is a hollow ball of cells. The blastocyst implants in the uterine wall, where it grows into an embryo attached to the placenta and surrounded by a fluid-filled membrane.

Complete answer:
Apomixis is the replacement of traditional sexual reproduction with asexual reproduction that does not require meiosis or syngamy. The two main types of apomixis are
Agamospermy, or recurrent agamospermy, is the development of a seed with an embryo that has not undergone meiosis or syngamy. There are two kinds of it: non-recurrent and recurrent. The embryo in non-recurrent agamospermy is haploid.
Adventive Embryony (Sporophytic Budding): occurs when an embryo emerges directly from a diploid cell other than an egg, such as the nucellus and integument of a plant, such as Citrus and Opuntia. Polyembryony, or the phenomenon of developing more than one embryo, is the result of this. In an embryo sac, there may be more than one egg cell, and in an ovule, there may be more than one embryo sac.

So the correct answer is option B

Note:
As a result, it resembles asexual reproduction. Apomixis is a form of plant reproduction that resembles sexual reproduction but produces seeds without fertilisation, as seen in some Asteraceae and grass species.
