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.
An embryo in the cell reorganization stage of development.
Gastrula!!!!
blastopore
In order: meiosis in parents (creates gametes), fertilization, zygote, cleavage, blastula, gastrula, adult (obviously after baby is formed and born).
The blastula is an embryonic structure that is formed from one cell layer. This later forms the three cell layered gastrula. All of the layers of the organism are formed from these three layers. See the link below:
endoderm, mesoderm, then ectoderm
1) How is a Gastrula different from the Blastula?

Gastrula!!!!
Surely it is the gastrula. The fertilized egg contains only one copy of the genome, while the gastrula contains thousands copies of the genome.
The endoderm of the gastrula turns into internal organs such as the liver and pancreas, and into the lining of some systems.
no
blastopore
In order: meiosis in parents (creates gametes), fertilization, zygote, cleavage, blastula, gastrula, adult (obviously after baby is formed and born).
Blastula occurs first and then gastrula. The zygote turns into a morula through clevage and then blastula occurs. Just remember it as the morula BLASTing.
The cavity of a gastrula forming a primitive gut.
