Vedclass · Answer

(D) In angiosperms,the endosperm is formed by the process of double fertilization,specifically through the fusion of one male gamete $(n)$ with two polar nuclei ($n+n$ or $2n$ depending on the female parent's ploidy).Given that the male plant is diploid $(2n)$,its gametes are haploid $(n)$.Given that the female plant is tetraploid $(4n)$,its embryo sac is formed from a megaspore mother cell $(4n)$ via meiosis,resulting in haploid megaspores $(2n)$.Thus,the polar nuclei in the central cell of the embryo sac will each be diploid $(2n)$.The endosperm is formed by the fusion of one male gamete $(n)$ and two polar nuclei $(2n + 2n)$.Therefore,the ploidy of the endosperm is $n + 2n + 2n = 5n$,which is Pentaploid.

If an angiospermic male plant is diploid $(2n)$ and the female plant is tetraploid $(4n)$,what will be the ploidy level of the endosperm?

Endosperm of angiosperms results after fertilization from:

Assertion: Endosperm is a nutritive tissue and it is triploid.
Reason: Endosperm is formed by the fusion of the secondary nucleus with the second male gamete. It is used by the developing embryo.

In an angiospermic plant,endosperm is formed due to the fertilization of the secondary nucleus,but it is absent in some seeds,such as pea,bean,and Phaseolus (moong). This is due to the lack of:
