Methods of embryo fertilization and development factors

Margareta Sam

An embryo is an original stage of development of a multicellular organism. In organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization of the womanish egg cell by the manly sperm cell. The performing emulsion of these two cells produces a single- celled zygote that undergoes numerous cell divisions that produce cells known as elastomers. The elastomers are arranged as a solid ball that when reaching a certain size, called morale, takes in fluid to produce a depression called a blastocoel. The structure is also nominated a blastula, or a blastocyst in mammals.
