The statement that says that In "gastrulation" cells begin to differentiate and they form different types of tissues so that they can accomplish different purposes in the body, is true.
Explanation:
Gastrulation involves a process of cell division, migration and differentiation, being one of the stages of embryonic development.
Cell differentiation and migration in gastrulation leads to the formation of germ layers, which are responsible for forming different tissues and fulfilling different functions in the body:
<em>The outermost lamina is called the </em><em>ectoderm</em><em>, which can give rise to nerve tissue and part of the skin tissue.
</em>
<em>The </em><em>mesoderm</em><em> is the middle lamina, and from it vascular, bone, muscle, and joint tissue can develop, as well as tissues of excretory and reproductive organs. </em>
<em>Endoderm</em><em> corresponds to the internal lamina, forming in great part the mucous membrane of the organs of the digestive system.
</em>
It is true, then, that <u>In gastrulation cells begin to differentiate and form different types of tissues so they can accomplish different purposes in the body</u>.
