This can determine birth defects, and much more depending on where the cell is.
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.
Cellular induction is a technique of producing specific morphogenetic effect in the developing embryo. This process uses the influence of evocators or organizers.
In short, an embryo undergoes both cellular division and cellular differentiation to become a fetus. This is achieved by the genetic program present in the cell(s) which controls both mentioned processes. It is the stage of developing mammal.After 9th week of fertilisation,the embryo can be called foetus.
Embryo is produced by cell division of zygote .
Organogenesis is the process by which a mass of cells in a developing embryo differentiates and develops into a functioning organ. In the embryo, all cells are basically stem cells and all alike. Once the process of organogenesis takes place and the beginnings of specialized organs form, the fetal stage begins.
This can determine birth defects, and much more depending on where the cell is.
A special :)
An angioblast is a cell which differentiates into blood cells and endothelium within an embryo.
A bulb is a giant embryo. It is still living, but it is multicellular. A giant cell would be a yolk thingy, or a developing chicken in its egg. A bulb is not a cell.
Stem cells are pluripotent, that is, they have the ability to differentiate and become any cell type in the body.
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.
After fertilization while the egg is developing into an embryo, a cell may split off and form a separate fetus.
Cellular induction is a technique of producing specific morphogenetic effect in the developing embryo. This process uses the influence of evocators or organizers.
Mitochondria
it is in every cell. it is located within the nucleus.
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.
