Question

In a flower, male gametes are formed from
A. Vegetative nucleus
B. Generative nucleus
C. Primary endosperm nucleus
D .Synergid nucleus

Answer 1

Hint:-The part of the male gamete—the sperm cell—during the time spent preparing is to perceive, stick to, and intertwine with the female gamete. These exceptionally specific capacities are relied upon to be constrained by the initiation of a novel arrangement of qualities.

Complete Answer:-A binucleate angiosperm dust grain containing a generative core and a cylinder core. After the dust grain develops into a dust tube, the generative core isolates into two sperm cores. Since the generative core and sperm cores contain cytoplasmic sheaths, they are regularly alluded to as cells in certain course books. The cylinder core controls the development of the dust tube as it becomes down the style and into the ovary of a blossom. In the end, it infiltrates the micropyle of an ovule and deliveries its two sperm into the 8-nucleate undeveloped organism sac. During twofold preparation, one sperm wires with the egg core to frame a zygote. The other sperm wires with the two polar cores inside the endosperm mother cell to shape the endosperm. In corn, this cycle must happen for each grain that structures. Much additionally astounding is the development of discrete dust tubes down each strand of silk (styles).

Note:- The dust grain has two cores called the cylinder core and the generative core. After the cycle of fertilization, a dust tube is developed by dust grains that travel through the disgrace and style and arrive at the ovules in the ovary and afterward the generative core partitions to frame two male gametes in which one wire with egg and other with polar cores.
