An embryo is an early stage of development of a multicellular diploid eukaryotic organism. In general, in organisms that reproduce sexually , an embryo develops from a zygote , the single cell resulting from the fertilization of the female egg cell by the male sperm cell. The zygote possesses half the DNA from each of its two parents. In plants , animals , and some protists , the zygote will begin to divide by mitosis to produce a multicellular organism. The result of this process is an embryo.

The fields of biology, medicine, and embryology have described the developmental milestones of humans throughout gestation in great detail. It is less clear as to when humans are recognized as people, persons, or beings with rights that are protected by legislation. The practice of law is irrevocably intertwined with that of ethical conduct; and the time at which a human life is considered a person has implications that extend to health care, legislation on abortion, and autonomy of individuals. This article reviews the economical position that fertilization is the moment that personhood of the conceptus begins. Alternate positions proposing that personhood begins at other possible times after fertilization are presented and contrasted to the economical hypothesis. Summary : This article is an original work critically analyzing the various arguments for human personhood at fertilization and thereafter.

The embryo refers to the first stage of development of a baby from the moment of fertilization. It is called a fetus from the eighth week of conception. There are developmental differences between the two stages and a lot of difference that the mom faces while she is carrying them. The embryo is the first thing you notice when you go for a pregnancy test. It is the size of a sesame seed at the time you go for your first ultrasound. By the fifth week of development, the embryo will display a heartbeat in the early ultrasounds. As time progresses, the tiny embryo will develop buds in its form that develop into hands and legs.

It is common for people to not be too familiar with at least one of these three terms, especially if they are not medical professionals. From a fertilized cell to a fully developed fetus, let us see how different these stages are and why each is very important. A zygote is a cell fertilized by the union of the ovum i. It contains the DNA from both its parents. The zygote then multiplies and develops through the process of cell division to form the embryo. The zygote is the first stage of development of the fertilized cell. While it is common for animals to keep the zygote inside their bodies, other animals including birds and most reptiles lay eggs where the zygote develops.
