Question

Of the animals, how does the individual's body develop and organise its different parts and what are the specialised organs found for different fuctions?

Answer 1

In humans the individual's body develop and organize into different parts through a process called gastrulation. Gastrulation is the transformation of the blastocyst into the gastrula with primary germ layers by rearrangement of the cells. The three germ layers are ectoderm, endoderm and mesoderm. Each germ layer gives rise to specific tissues, organs and organ systems.
