Every living organism on this planet comes through the wonderful process of growth which starts from the sexual reproduction up to the giving birth. This process includes the microcellular growths in every female organism like the humans. In these processes, the stages called the zygote and the embryo, which are actually the initial stages of the life of an organism. But these two are often having some confusing issues about their meanings and differences.
The zygote starts as unicellular and is formed in the fertilization after the paternal gene pool’s derived gamete arrives and meet the maternal gene pool’s derived gamete. This is the explanation on why is zygote is the first stage of the life of an organism which. This stage is in unicellular structure and is the product of the genetic material fusion of the parents during the sexual reproduction.
The embryo is also one of the initial stages of a eukaryotic animal’s life cycle. But compared to the zygote that starts as unicellular, the embryo is a eukaryotic multicellular organism that is in the earliest stage which is formed by the process called embryogenesis. This process occurs only when after the zygote has done the formation.
