Question

Which of the following statements about double fertilization in angiosperms is correct? One pollen grain combines with the egg to form the zygote, and one pollen grain combines with the polar nuclei to form endosperm. Two sperm combine with a polar nucleus to form endosperm. Two pollen grains combine with two ovules to form the zygote and endosperm. One sperm combines with the polar nuclei to form the zygote, and one sperm combines with the egg to form endosperm. One sperm combines with the egg to form the zygote, and one sperm combines with the polar nuclei to form endosperm. Save Which of the following occur during the formation of an embryo from a zygote in angiosperms? The root and shoot systems emerge from the seed.

Explanation / Answer

Answer:

4). One sperm combines with the egg to form the zygote, and one sperm combines with the polar nuclei to form endosprm

Embrysac consists of 8 nuclei and 7 celled stage. Two sperms involve in the double fertilization of angiosperms. One sperm fuses with egg to produce diploid zygote and the other sperm fuses with two polar nuclei that are fused and present at the center. So the second sperm fuses with diploid nucles to produce triploid endosperm.
