During Fertilization In Flowering Plants
During fertilization in flowering plants, one sperm cell fuses with an egg cell to form a zygote and a second sperm fuses with two polar nuclei to form _____________.
Correct B ) endosperm
he process by which one of the two sperm nuclei fuses with the egg nucleus to produce a diploid zygote and the other fuses with the polar nuclei to produce a triploid endosperm
the transfer of pollen grains from an anther to the stigma of the same flower or to the stigma of another flower on the same plant
For questions 1 and 2 please refer to lesson 7 activity 16, “Life Cycle of an Angiosperm”, and use the websites listed below. For question 4 please refer to lesson 7 activity 12, “Fertilization of a Flower”, and the websites listed below.
