A unmarried bacterium, which is single unrivaled cubicleed organism, send word divide into both new one prison jail celled organism. This process of cell division is called mitosis for most one celled organism or binary fission for procaryotic cells.As female and male human being mate, the chunk of a female becomes fertilized by the sperm of the male. Although arthropods comparable grasshoppers also mate, the pelt of a grasshopper contains a elflike yolk to support the egg cell when it develops subsequently fertilization. Since the yolk is small, several semen cells contained in a single egg support the primary germ cell providing plyment after fertil ization. Human ballock do not postulate yolk, after fertilization the developing baby is nourish by the mother through the umbilical cord cord.Another group of animals living in the irrigate also differ from human egg.
