One of the changes that would occur in an ovary of flowering plants after double fertilisation is that the
Correct answer: C. Polar nuclei will form triploid endosperm
- A. Pollen tube will disappear
- B. Antipodal cells will double in number
- C. Polar nuclei will form triploid endosperm
- D. Egg cell will fuse with synergids to form diploid zygote
Explanation
In flowering plants, double fertilization involves two key events: one sperm cell fuses with the egg cell to form a diploid zygote, and the other sperm cell fuses with the two polar nuclei to form a triploid cell that develops into the endosperm. Therefore, the correct answer is Option C: polar nuclei will form triploid endosperm. The other options describe processes or changes that do not occur in the context of double fertilization or within the ovary following this event.

About Embryonic Development
Embryonic development begins after fertilization with cleavage and formation of the morula and blastula, followed by gastrulation and the establishment of germ layers. It includes organ formation, tissue differentiation and early growth, rather than the later increase in size associated with postnatal development.
