What is formed when the male germ-cell from the pollen grain fuses with the female gamete in flowering plants?
Pollen grain
Zygote
Stigma
Ovule
Zygote
In flowering plants (angiosperms), fertilization involves the fusion of the male gamete (from the pollen grain) with the female gamete (egg cell) located within the embryo sac. This process results in the formation of a diploid cell known as the zygote.
In flowering plants (angiosperms), fertilization involves the fusion of the male gamete (from the pollen grain) with the female gamete (egg cell) located within the embryo sac. This process results in the formation of a diploid cell known as the zygote.
Think of it as a biological 'lock and key' mechanism where the pollen (key) meets the egg (lock) to unlock the creation of a new generation (the seed/zygote).
P + E = Z (Pollen + Egg = Zygote)
n+n=2n тАФ Haploid male gamete (n) plus haploid female gamete (n) forms a diploid zygote (2n).
The process is known as syngamy or generative fertilization. Upon pollination, the pollen grain produces a pollen tube that grows down the style to reach the ovule. The male gametes are released into the embryo sac, where one fuses with the egg cell to form the zygote, while the other fuses with two polar nuclei to form the primary endosperm nucleus (triple fusion).
Fertilization is the fusion of two haploid gametes to produce a diploid zygote.
Flowering plants exhibit a unique process called double fertilization.
The zygote eventually develops into the embryo inside the seed.
Ensures genetic diversity through sexual reproduction.
Allows the embryo to remain protected inside a seed until conditions are favorable.
Agricultural crop breeding.
Understanding plant reproductive health.
Option A (Pollen grain) is the male gametophyte, not the product of fusion.
Option C (Stigma) is the female part of the flower that receives the pollen.
Option D (Ovule) is the structure that contains the female gamete and eventually becomes the seed.
B is correct тАФ The fusion of the male germ-cell and the female gamete produces a diploid zygote.
Always remember that in plants, double fertilization occurs: one fusion forms the zygote (2n) and the other forms endosperm (3n)!
