What else can I help you with?
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 is endosperm haustorium?
The endosperm haustorium is a structure formed by the developing embryo in some plant species to absorb nutrients from the endosperm. It allows the embryo to obtain essential nutrients for its growth and development during seed germination. The endosperm haustorium eventually withers away as the embryo becomes self-sufficient.
How are the embryo and the endosperm formed in a plant?
For an endosperm to be formed one sperm nucleus has to fertilize the egg. The egg is fertilized to form a zygote while the other sperm nucleus fuses with the two polar nuclei at the center of the embryo sac to form the primary endosperm cell.
Triploid endosperm nucleus is a result of?
Triploid endosperm nucleus is a result of double fertilization in angiosperms, where one sperm fertilizes the egg cell to form the diploid zygote and the other sperm fertilizes the central cell to form the triploid endosperm. The endosperm serves as a nutrient source for the developing embryo.
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 function of endosperm in monocot and dicot seed?
The endosperm in monocot seeds serves as a nutrient reserve that provides nourishment to the developing embryo. In dicot seeds, the endosperm is often absorbed by the developing embryo during seed maturation, leaving the cotyledons to function as the primary nutrient storage tissue.
What is the function of the embryo in a flower?
endosperm and dicot
What is the fate of egg and endosperm nucleus in double fertilization of plant?
During double fertilization one male gamete fuses with egg nucleus to form zygote and the other with primary endosperm nuclei in tripple fusion to form endosperm nucleus.
What is the function of the endosperm?
to provide nourishment to the developing embryo in a seed
What are the end products of double fertilisation?
the end products of double fertilisation are primary endosperm cell and diploid zygote. When two pollen grains are taken by pollen tube and it reaches a ovule in the ovary. One germ cell fuses with egg and form zygote which later develops into embryo and other germ cell fuses with bi-nucleate cell and form primary endosperm cell which later develops into endosperm which provide nutrition to the growing embryo.
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 is the primary function of t4?
waht is a primary function in computer?
What are the 5 parts of a seed?
The five parts of a seed are the seed coat, endosperm, embryo, cotyledons, and radicle. The seed coat provides protection, the endosperm stores nutrients for the embryo, the embryo is the young plant-to-be, the cotyledons are the first leaves to emerge, and the radicle is the embryonic root.
What is the primary function of the primary system?
The primary function of the reproductive system is to generate new species. This function is commonly referred to as procreation.
What is the primary function of the stomach?
The primary function of the stomach is to digest food.
What is the primary function of a landfil?
The primary function of a landfill is to decompose trash
Name an example of a seed that has liquid endosperm?
An example of a seed that has liquid endosperm would be a coconut. While it does contain cellular endosperm, the coconut milk would be considered liquid endosperm.
