Differentiation is important during embryonic development as that is the timeframe for specialization. Differentiation allows for neurons, blood cells, skin and muscle cells organize into tissues, then organs, and ultimately into systems.
Without differentiation the embryo would not develop different organs or organ systems. It would essentially be one uniform tissue.
terminal cell : provide polarity to the embryo and embryo develops here.. (apical cell) basal cell : develops suspensor which anchors embryo to the endosperm and serve as a nutrient producer.
I think it's when a stem cell from an embryo is taken and has repaired a tissue. (I think) Anyone else know?
In human development, the first cell divisions occur in the salpinx of the woman, before the embryo is implanted in the uterus
Embryo biopsy is the process of removing a cell from an embryo, usually at three days of development. Preimplantation genetic diagnosis (PGD) is the act of performing genetic testing on the cell that has been removed from the embryo before that embryo is transferred to the uterus. In other words, embryo biopsy is necessary in order to perform PGD. Shannon DeWall, MS, CGC Genetic Counselor and Program Coordinator Genesis Genetics Institute
Fetus (Pronounced 'Feetus')I did the names in bold:Oocyte -> fertilization -> Fertilized Ovum-> cleavage (cell division) -> Morula -> Blastocyst -> attachment to Uterine wall -> Implantation -> Embryoblast -> Embryo -> After the first two months of development, the embryo is called a Fetus until birth

cell, zygote, embryo then fetus!
The cell divides.
A gastrula is an embryo in the cell organization of development, when the three germ layers form. This is called gastrulation, and the three layers are the endoderm, mesoderm, and ectoderm. A neurula is an embryo at the stage of development when the nervous system begins developing, called neurulation. Neurulation happens after gastrulation.
All stages of fetal development are important. The stages where the fetal development are most susceptible to developmental problems are the earliest ones. This is because the embryo starts out as one cell and then multiplies itself. This is the most crucial and vulnerable part of development because there are so few cells that any abnormality in the embryo's environment can lead to defects and even still birth.

An embryo is a multicellular diploid eukaryote in its earliest stage of development , from the time of first cell division until birth, hatching, or germination . In humans, it is called an embryo until about eight weeks after fertilization

At the first cell division of the zygote (fertilized egg), according to Wikipedia: http://en.wikipedia.org/wiki/Embryo

Abnormalities like that happen from cell mutations. Other times, they happen when a twin embryo is initially formed but is partially assumed by the other embryo as development begins.
embryology has an important role in the animals as it tell us the ontogenic development of an organism.it helps us to understand how an embryo undergoes different changes to reach the adult stage...i.e its growth,cell division and cell differentiation can be well studied in embryology.
