A structure grown by a pollen grain that contains two sperm nuclei is called what?

The structure grown by a pollen grain that contains two sperm nuclei is called the pollen tube. The pollen tube is responsible for delivering the sperm nuclei to the ovule for fertilization in plants.


Whats the word for cells with many nuclei?

A cells with many nuclei is often called a syncytium. The normal cell structure for many types of fungi is a syncytium.


What is it called when a Sperm Cell finally reaches an Egg Cell?

This is called FERTILIZATION. It means that the specific sperm cell that would later become a child, when the nuclei of the egg and sperm cell, joins with the egg. The fetus will begin to form when the nuclei of the two cells join, however it may take a while until the fertilization is complete.


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.


Why do endosperm formation does not occur until fertilization take place?

Endosperm formation is triggered by fertilization because it involves the fusion of the two sperm cells with different nuclei in the embryo sac, leading to the triploid (3n) condition necessary for endosperm development. Without fertilization, the endosperm would not receive the necessary genetic contribution to develop properly and support the growing embryo.

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 term used to describe cells that have nuclei?

Why isn't fertilization considered to be complete until the nuclei of the two cells joined together?

because there needs to be a full set of chromosomes, 46
