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.
A triploid cell resulting from double fertilization becomes the what?
A triploid cell resulting from double fertilization becomes the endosperm, which provides nutrients to the developing embryo in plants.
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.
What process in angiosperm produces a diploid zygote and a triploid endosperm?
Double fertilization in angiosperms produces a diploid zygote and a triploid endosperm. This process involves one sperm cell fertilizing the egg cell to form the zygote, while another sperm cell fuses with the central cell to form the endosperm.
If the chromosome no of a plant is 16 what would the chromosome no of the ploidy level of the microspore mother cell and the endosperm cells be?
If the chromosome number of a plant is 16, then the ploidy level of the microspore mother cell would be 2n=16 (diploid) and the endosperm cells would typically be 3n=24 (triploid), as they result from the fusion of a haploid sperm cell and a diploid central cell in double fertilization.
The triploid nucleus in the megaspore divides to produce?
The triploid nucleus in the megaspore divides to produce endosperm, which provides the plan embryo in the seed with food.
What is the 3n nutritive tissue in the seed of angiosperms called?
the triploid The endosperm is a nutritive tissue which nourishes the developing embryo. The endosperm in angiosperm is triploid (3n) and it is a post - fertilization structure.
What is the Triploid stage of a flowering plant?
The triploid stage of a flowering plant occurs during fertilization when the male and female gametes combine to form a triploid zygote. This triploid zygote then develops into the endosperm, which provides nutrients for the developing embryo in the seed. The triploid endosperm typically contains three sets of chromosomes, one from the male and two from the female parent.
Is there is endosperm present in gymnosperm?
No, triploid endosperm is in angiosperms only. Gymnosperm means "Naked Seed."
Why do endosperm formation does not occur until fertilization take place?

What is the ploidy of cells of aleurone layer in cereal grains?
The aleurone layer is the outermost layer of the endosperm. Therefore it is also triploid and same as the ploidy of endosperm.
What is the ploidy level of endosperm of gymnosperm?
Endosperm of gymnosperm is haploid(ploidy n), develop from megaspore (n) before fertilization. ploidy of endosperm in angiosperm is 3n(central cell fused with one male gamete i.e 2n+n).
What process in angiosperm produces a diploid zygote and a triploid endosperm?
Double fertilization in angiosperms produces a diploid zygote and a triploid endosperm. This process involves one sperm cell fertilizing the egg cell to form the zygote, while another sperm cell fuses with the central cell to form the endosperm.
What is the name given to the triploid structure that provides food storage for the developing embryo in angiosperms?
endosperm
If the chromosome no of a plant is 16 what would the chromosome no of the ploidy level of the microspore mother cell and the endosperm cells be?
If the chromosome number of a plant is 16, then the ploidy level of the microspore mother cell would be 2n=16 (diploid) and the endosperm cells would typically be 3n=24 (triploid), as they result from the fusion of a haploid sperm cell and a diploid central cell in double fertilization.
