Solution
The correct option is B Coenocytic nucleus
During the double
fertilization in angiosperms, one of the two male gametes carried by the pollen
tube fuses with the egg cell nucleus to form the diploid central cell nucleus
to form endosperm.
The initial stage in the development of endosperm is considered
as cell proliferation, leading to the formation of a syncytium composed of
numerous free nuclei within the cytoplasm, enclosed in a single common
membrane.
As endosperm formed by the fusion of a diploid nucleus and a haploid
nucleus and a haploid gamete hence it is triploid structure.
A coenocytic nucleus is a multinucleate cell which can be obtained from multiple nuclear divisions without their accompanying cytoplasmic division. So, the correct answer is option C.
