the endosperm
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.
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).
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.

the endosperm
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 embryo is formed from fertilization of the egg cell by the sperm cell, containing genetic material from both parents. The endosperm is formed from the fusion of the second sperm cell with the central cell in the ovule. The seed is formed when the embryo and endosperm are enclosed within the protective seed coat after fertilization.
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.
A triploid cell resulting from double fertilization becomes the endosperm, which provides nutrients to the developing embryo in plants.
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.

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).
The embryo is formed through fertilization of the egg cell by the sperm cell. This union creates a zygote that develops into the embryo. The endosperm, on the other hand, is formed through the fusion of a sperm cell with two polar nuclei in the embryo sac of 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.
Endosperm that contains starch will turn blue-black when iodine solution is applied, indicating the presence of starch in the endosperm cells. This color change occurs due to the formation of a complex between iodine and starch molecules.
