the pollen tube enters the ovule at a point called the
Pollen tube Angiosperm reproduction is a complex process that includes several steps that may vary among species.[1] Each step is a vast procedure in its own right. Pollen is produced by the stamen, the male reproductive organ of the flower. Each pollen grain contains a vegetative cell, and a generative cell that divides to form two sperm cells. The pollen is delivered by the opening of anthers for subsequent pollination, that is, for the transfer of pollen grains to the pistil, the female reproductive organ. Pollination is usually carried out by wind, water or insects. The ovaries hold the ovules that produce the female gamete: the egg cell, which waits in place for fertilization.
Vapor–liquid separator For the common variety, gravity is utilized in a vertical vessel to cause the liquid to settle to the bottom of the vessel, where it is withdrawn.[1][2][3][4]
Vein Veins are less muscular than arteries and are often closer to the skin. There are valves in most veins to prevent backflow.
