Endosperm formation requires the investment of a lot of nutrients. If it took place earlier, and fertilization did not occur, those nutrients could be wasted.

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 are the two distinct fertilization that take place in angiosperms?

What are the two distint fertilization that happen in endosperm


What role does double fertilization play in the life cycle of angiosperms?

The fusion of a male gamete with secondary nucleus is called double fertilization and it results in the development of endosperm which nourishes the developing embryo inside the seed. Thus without double fertilization nourishment of developing embryo will be hamphered.


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.


Where is the place where pollen lands for pollination to occur in a flower?

Pollen lands on the stigma, which is the sticky female reproductive part of the flower, during pollination. This interaction allows for fertilization and the formation of seeds.


Where does the fertilization takes place?

Depending on the animal, fertilization of eggs can occur externally or internally. With internal fertilization...the sperm and egg generally combine in the fallopian tubes.


Which process must occur before any division can take place?

Fertilization


What would happen if the sperm could not get into the egg?

If the sperm cannot get into the egg, fertilization cannot occur and pregnancy will not take place. The egg needs to be fertilized by the sperm in order for the genetic material from both to combine and form a zygote, which will eventually develop into an embryo.


What plant part fom the seed?

The seed is formed in the fruit from ovule. A fertilized ovule develops the embryo and endosperm. Most of the endosperm is used up by the developing embryo in dicot seeds. In monocot seeds large amount of endosperm is retained to support the germinating embryo. When someone plants a seed in the ground an entire plant grows from it over time.


When at which stage is fertilization occur?

Fertilization occurs when a sperm cell successfully penetrates and merges with an egg cell, typically within the fallopian tubes of the female reproductive system. This event usually takes place shortly after ovulation, when an egg is released from the ovary and is viable for fertilization for about 12 to 24 hours. Once fertilization occurs, it leads to the formation of a zygote, which will begin the process of cell division and eventually implant into the uterine lining.


What type of fertilization and development occur in the zebrafish?

Zebrafish exhibit external fertilization, where the female releases eggs and the male fertilizes them outside of the body. The embryos develop externally, with the early stages of development taking place outside of the mother's body in the water.


When does fetilization occur?

Fertilization occurs when a sperm cell successfully merges with an egg cell, typically in the fallopian tube of a female's reproductive system. This process usually takes place within 24 hours after ovulation, when an egg is released from the ovary. Once fertilization occurs, it results in the formation of a zygote, which will begin to divide and eventually implant in the uterine lining.
