What else can I help you with?
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.
What is the Joining of nuclei and chromosome?
fertilization
What happen to polar nuclei after fertilization?
endosperm
The joining of nuclei and chromosomes is know as what?
Fertilization
What causes an ovary to develop into a fruit?
Fertilization of sperm-nuclei.
What is the joining of the nuclei from a pollen grain to those of an ovule called?
Fertilization
What is the process called when the egg and sperm combint the contents of their nuclei?
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.
Is pollar nuclei a haploid or a diploid?
Polar nuclei are typically haploid. In the context of plant reproduction, specifically within the embryo sac of angiosperms, polar nuclei are formed from the fusion of two haploid nuclei. These nuclei eventually contribute to the formation of the triploid endosperm when fertilization occurs.
What is the joining of a male and female nuclei called?
The joining of a male and female nuclei is called fertilization. This process typically occurs during the fusion of sperm and egg cells, resulting in the formation of a zygote. Fertilization is a crucial step in sexual reproduction, leading to the development of a new organism.
What does cross fertilization mean?
a. the union of male and female gametic nuclei. b. the enrichment of soil, as for the production of crops.
What happens to the egg and the sperm during fertilization?
The nuclei of the egg and sperm cells fuse to form the fertilized egg.
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.
