The given diagram shows an unfertilised angiosperm ovary.What change would take place in the ovary after double fertilisation?
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 a synergid to form diploid zygote
Explanation
In angiosperms, double fertilization involves two key events: one sperm cell fuses with the egg cell to form a diploid zygote, and another sperm cell fuses with two polar nuclei to form a triploid endosperm. The triploid endosperm is crucial as it provides nourishment to the developing embryo. So option C is correct.
