3 Divisions.
In Division 1, the original cell (the gamete) divides in 2.
In Division 2, the two cells from the first division both divide in 2, giving a total of 4 cells.
In Division 3, the 4 cells from the second division all divide in 2 giving a total of 8 cells.
The next stage after the zygote stage is the embryo stage. During this stage, the zygote undergoes multiple cell divisions and starts to differentiate into the various cell types needed for development.
A 12-cell embryo, also known as a morula, is in the early stages of development but is not yet fully prepared for implantation in the uterus. Typically, implantation occurs after the embryo reaches the blastocyst stage, which usually happens around day 5 post-fertilization. At this stage, the embryo has developed a fluid-filled cavity and differentiates into an inner cell mass and an outer trophoblast layer, which are essential for successful implantation. Therefore, while a 12-cell embryo is an important step in development, it is not yet capable of implanting.
That is called an embryo, which is the earliest stage in the development of an organism. It is the stage where the organism's basic body structures start to form.
An animal embryo that has been created with animal egg and sperm. At an early stage of development, human cells are added to the embryo. The embryo will go on to develop and contain functioning human cells.
Totipotent stem cells are primarily found in the earliest stages of embryonic development, specifically in the zygote and the first few divisions of the embryo, up to the 8-cell stage. These cells have the potential to develop into any cell type in the body, including both embryonic and extraembryonic tissues. After this stage, cells become pluripotent, meaning they can differentiate into almost any cell type but cannot form an entire organism. Therefore, the greatest number of totipotent stem cells is present in the very early embryo, particularly before the 8-cell stage.
The next stage after the zygote stage is the embryo stage. During this stage, the zygote undergoes multiple cell divisions and starts to differentiate into the various cell types needed for development.
The first stage of an embryo from an egg is the cleavage stage, where the egg undergoes rapid cell divisions without growth, producing smaller cells called blastomeres. This stage eventually leads to the formation of a multicellular embryo.
The zygote develops into a blastocyst as it undergoes multiple divisions. This stage occurs before implantation in the uterus.
embryo
An embryo is typically considered to be in the stage of development from conception to around 8 weeks after conception. At this stage, the embryo is rapidly growing and developing its major organs and structures.
An Embryo is a stage before Fetus, the Fetus is more developed than an Embryo, the stage of Birth and a baby being more developed than a fetus.
Gastrulation
It is a unborn baby, after the first few cell divisions following fertilization and before becoming a fetus. An embryo bears little or no resemblance to a baby, but a fetus is clearly recognizable as a tiny version of a baby.The two month old baby
it is an embryo
The earliest stage of an embryo is the zygote, which forms when a sperm fertilizes an egg. This single-cell stage begins the process of cell division and development into a multicellular organism.
A 12-cell embryo, also known as a morula, is in the early stages of development but is not yet fully prepared for implantation in the uterus. Typically, implantation occurs after the embryo reaches the blastocyst stage, which usually happens around day 5 post-fertilization.

Therefore, while a 12-cell embryo is an important step in development, it is not yet capable of implanting.
Blastocyst stage follows the morula stage of embryo development.
