exoderm
During blastula there will be two germ layers 1)ectoderm 2)endoderm, after gastrulation , there will be three germ layers 1) Ectoderm 2) Endoderm 3) Mesoderm
Gastrulation
Gastrulation is defined as a phase early in the embryonic development of most animals, during which the single-layered blastula is reorganized into a trilaminar structure known as the gastrula. These three germ layers are known as the ectoderm, mesoderm, and endoderm. These develop into the respiratory and digestive organs.
Blastulation is when the cells move to form a hollow "ball". Gastrulation is when it bends upon itself to make 3 layers, called the endoderm, the mesoderm, and the ectoderm.

yes :)

Gastrulation
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.
Three distinct layers form during gastrulation: ectoderm, mesoderm, and endoderm. Each contributes to different organs.Some examples are:Ectoderm = skin, brainMesoderm = kidneys, muscleEndoderm = digestive tract, respiratory tract
