Embryo is called the organism produced by copulation or sexual act, when it is in full stage of development, understand this phase, when the cells of the embryo divide and take on their characteristic functions. From the fertilization process, in the ovum or the egg (depending on the type of reproduction) an element called Zygote is formed, this during the first 7 weeks of gestation, generates cells and expands until it achieves an area for itself capable of housing the organisms that make up the embryo.

The embryo is the stage in which these organisms take possession of the aforementioned area, each cell develops composing the organisms that constitute the body. In the case of human beings, reproduction that occurs through the introduction of a sperm provided by the man in the woman’s egg, while the zygote constitutes the area to recreate the formation of cells in organs can take between 7 to 8 weeks. After this period, while the embryo takes its shape, the DNA of the parts involved are combined, defining the chromosomal identity of the embryo. This does not imply that the sexuality of the organism is visualized, however, this process takes place while the development of the body is fundamentally based on the position and distribution of cells.

In Botany, they also refer to the term embryo, when the plant is in the minimum expression of its development. These organisms are in a state of inactivity in which their cells reproduce all the necessary components before they flourish. The embryos of the botanical flora, reproduce at the cellular level in a simpler way than the animal, however, there are similarities in the process, such is the case of the presence of the zygote, which contains the cells that at the individual level are they will be configured until they form the embryo, this process is known as embryogenesis, which consists of all the physiological and transformation processes that lead to the formation of the botanical organ. In either case, the term embryo is used to differentiate a stage of development.
