What is gastrula?
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.
What blastocyst produce the primordial germ cell?
Gastrula (early gastrula follow the blastula in the development sequence) ~ As a result of gastrulation, a three-layered embryo forms, each layer corresponding to a primary germ layer from which all body tissues develop.
What primary germ layers of the embryo does the epidermis of the skin develop from?
The outermost, middle, and innermost layers are the ectoderm, mesoderm, and endoderm, respectively.
Why is it necessary for the germ line to become separated at such an early stage of development?
The more times a cell divides, the more likely that errors will occur in DNA replication. By separating the germ line early in development, it reduces the chances of a mutation.
How are the embryo and the endosperm formed in a plant?
For an endosperm to be formed one sperm nucleus has to fertilize the egg. The egg is fertilized to form a zygote while the other sperm nucleus fuses with the two polar nuclei at the center of the embryo sac to form the primary endosperm cell.
What marks the beginning of germs layer development in an embryo?

What is gastsrulation?
Gastrulation is a phase early in the development of most animal embryos, during which the morphology of the embryo is reorganized to form the three germ layers: ectoderm, mesoderm, and endoderm.
