Question 3

location of ectoderm and parts?

Answer 3

the outermost layer of cells or tissue of an embryo in early development, or the parts derived from this, which include the epidermis and nerve tissue.

what is the function of the neural plate?

Answer 4

is a key developmental structure that serves as the basis for the nervous system. Opposite the primitive streak in the embryo, ectodermal tissue thickens and flattens to become the
