The native sperm cells get through the pollen tube

Sperm nuclei, sperm cells - arise from an unobstructed generative cell located in the pollen grains (male gametes with a chromosome number = 1n). In many species, sperm cells are formed before the pollen leaves the pollen pouch. In others, the generative cell division occurs only after the production of the leopard. Sperm cells have no flagellar, and for delivery to the ovum corresponds to the pollen tube formed from the vegetative pollen cell. In the case of occipital plants, one of the sperm nuclei connects to the nucleus of the egg and the other is merged with two polar nuclei or the diploid nucleus of the central cell. From the fertilized central cell, triploid esophagus is developed.

The earliest mention of these creatures is dated to the fifth century BC, and its author is Herodotus. According to her, these ants inhabited the deserts of Persia and India and extracted gold from their sands. Several such creatures were kept in the residence of the King of Persia. Gold was to be obtained by caravans made up of several camels in the heat of the day, when the ants were protected underground. You had to do it quickly, because the ants sensed the smell of people and went on the pursuit, and they were deadly dangerous. This story is confirmed by the next accounts: Nearchos, one of the army officers of Alexander Macedoński, and Megastenes - a historian and traveler.
