In a fertilised embryo sac, the haploid, diploid and triploid structures are: a. Synergid, zygote and primary endosperm nucleus

(a) Ovary Diploid (2n) (b) Anther Diploid (2n) (c) Egg Haploid (n) (d) Pollen Haploid (n) (e) Male gamete Haploid (n) (f ) Zygote Diploid (2n)

Yes, if the embryo develops from the cells of nucellus or integument it will be diploid.

The triploid tissue in the ovule is the endosperm. Its triploid condition is attained due to the fusion of two polar nuclei and one nucleus of male gamete (also referred...

The zygote needs nourishment during its development. As the mature, fertilised embryo sac offers very little nourishment to the zygote, the PECdivides and generates the endosperm tissue which nourishes the zygote.Hence,...

It is true that many apomicts posses normal looking embryo sacs. The only possibility of the embryo sac possessing diploid cells is due to failure of meiotic division at the...

(i) When implantation has occurred in uterus of mother, the inner lining of the uterus thickens and is richly supplied with the blood vessels to provide nourishment to the growing...

b. Synergids and antipodals

b. The megaspores develops into an embryo sac, its nuclei would be Diploid

(A) for tir dic In the first and second statements, the common code word is green and the common word is sac.  So, green means sac. In the first and third...
