i)A zygote if formed due to the fusion of two gametes while endosperm is not from the fusion of two gametes.
ii)A zygote is of 2n condition while endosperm is of 3n condition
iii)A zygote later develops to a plant while endosperm provides nourisment to it.
iv)After fertilization it is a fact endosperm develops first then zygote so that the zygote gets the nourishment sufficiently.
1. Cotyledon (C) is formed from the embryo
Endosperm (E) is formed by the fusion of central cell nuclei and the second sperm (after double fertilization event)
2. C has E
Endosperm is the tissue produced inside the seeds of most flowering plants around the time that the egg (seed) is fertilized. It surrounds the seed embryo and provides nutrition in the form of starch, and can also contain oils and protein. This makes endosperm an important source of nutrition in human diet. For example, wheat endosperm is ground into flour for bread. http://en.wikipedia.org/wiki/Endosperm
A zygote is formed from the egg cell contributed by the female parent and an sperm from male parent. The fertilized egg is called a zygote, therefore, zygote is definitely a part of female reproductive cell.
The aleurone layer is the outermost layer of the endosperm. Therefore it is also triploid and same as the ploidy of endosperm.
There is no difference between the two products.
difference between cro and powerscope?
the endosperm
endosperm
Double fertilization
the endoSPERM searches for a egg cell and and forms a zygote around the process of iodine solution. WILL YOU EVER BELIEVE THIS DUDE?
There really isn't much difference between a zygote, embryo, and fetus. A zygote forms after fertilization and becomes an embryo, which later becomes a fetus.
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.
the zygote is dormant for sometime because it develops only after the endosperm develops. this is an adaptation to ensure nutrition to the growing embryo.
Fetus zygote is not the term to use. A zygote is a fertilized egg. An embryo is a developing baby. A fetus is a baby before it is born.

The "endosperm" of the bean seed is made of two leaf-shaped halves called cotyledons. Technically, it's not called an endosperm. However, the corn seed contains one 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.
angiosperm fertilization involves the so called "double fertilization" which is absent in gymnosperms. In angiosperms the secondary nucleus (formed from fusion of two polar cell nuclei) gets fertilized by the second male gamete along with fertilization of the egg cell of the embryo sac. The fertilization of the egg cell results in the formation of zygote whereas the fertilization of the secondary nucleus results in the formation of PEN (primary endosperm nucleus).PEN develops into endosperm while zygote into embryo. Perisperm provides the necessary nourishment to the developing embryo.
