What is the product of the fusion of a male germ-cell with the female gamete in an angiosperm?
Pollen tube
Zygote
Endosperm
Seed coat
Zygote
In angiosperms, the fusion of a haploid male gamete (n) with a haploid female gamete or egg cell (n) is called syngamy. This process results in the formation of a diploid (2n) cell known as the zygote.
In angiosperms, the fusion of a haploid male gamete (n) with a haploid female gamete or egg cell (n) is called syngamy. This process results in the formation of a diploid (2n) cell known as the zygote.
Think of it like a key (male gamete) perfectly fitting into a lock (egg cell) to open the door to a new life (the zygote).
Z for Zygote, Z for Zero to Zest (beginning of life).
n+n=2n тАФ represents the fusion of a haploid male gamete (n) and a haploid egg (n) to form a diploid zygote (2n).
The male gamete travels through the pollen tube to the embryo sac. Upon reaching the egg cell, the male gamete's nucleus fuses with the female egg nucleus. This fusion of two haploid nuclei restores the diploid chromosomal number in the zygote, which later develops into an embryo.
Syngamy is the primary event of sexual reproduction in plants.
Angiosperms exhibit double fertilization where one gamete forms the zygote and another forms the endosperm (3n).
The zygote is the first cell of the future sporophyte generation.
Ensures genetic variation through the combination of male and female DNA.
Plant breeding for crop improvement.
Seed production in flowering plants.
The zygote eventually undergoes mitotic divisions to develop into an embryo.
Option A is a structure for transport, Option C results from the fusion of a male gamete with two polar nuclei, and Option D is the protective outer layer of the seed.
B is correct тАФ The fusion of the male germ-cell and the female gamete results in the formation of a diploid zygote.
Remember that while the zygote is diploid (2n), the endosperm formed in the same process is triploid (3n) due to fusion with two polar nuclei.
