What is the result when one sperm fertilizes the polar nuclei in a flowering plant?
Double fertilization occurs in flowering plants, where one sperm fertilizes the egg to form a zygote, while the other sperm fertilizes the polar nuclei to form the endosperm. The endosperm provides nutrients to the developing embryo.
The joining of nuclei and chromosomes is know as what?
Fertilization
Where does the process of double fertilization occur in plants?
The Generative nucleus arrives at the embryo sac inside the ovule and undergoes division to produce two haploid male nuclei. One of the male nuclei fuses with the haploid female gamete nucleus and for a diploid zygote. The other Male nuclei fuses with 2 polar female gametes to produce the triploid nucleus. This is known as the endosperm nucleus and it acts as a food source for developing zygote.
What is the joining of the nuclei from a pollen grain to those of an ovule called?
Fertilization
How does double fertilization happen?
In double fertilization, one sperm reaches the egg and fertilizes it. This produces a diploid zygote that will grow into the plant embryo. A second sperm fuses with the endosperm nuclei in the embryo sac and produces the triploid endosperm. This will nourish the developing seedling.
What happens to the polar nuclei in an embryo sac?
The polar nuclei in an embryo sac are involved in the process of double fertilization in plants. One of the polar nuclei fuses with a sperm cell, leading to the formation of endosperm tissue, while the other polar nucleus may fuse with another sperm cell or remain unfertilized. The endosperm provides nutrients for the developing embryo in seeds.

What causes an ovary to develop into a fruit?
Fertilization of sperm-nuclei.
What is the process called when the egg and sperm combint the contents of their nuclei?
fertilization

Fertilization
What happens the nuclei of the egg and sperm during fertilization?
The nuclei of the egg and sperm cells fuse to form the fertilized egg.

Which member of the plant kingdom undergoes double fertilization?
Angiosperms (flowering plants) are the only members of the plant kingdom that undergo double fertilization. This process involves the fusion of one sperm cell with the egg cell to form the zygote and another sperm cell with the polar nuclei to form endosperm.
Is the primary endosperm nucleus haploid or diploid?
I am sure it is (3n).This is because In angiosperms most common type of embryo sac formation, there is fusion of 1 sperm nuclei + 2 polar nuclei=triple fusion resulting in a triploid primary endosperm nuclues.
