Question

short notes of primery germ layer

Answer 1

Answer:

A germ layer is a primary layer of cells that forms during embryonic development. ... Some animals, like cnidarians, produce two germ layers (the ectoderm and endoderm) making them diploblastic. Other animals such as chordates produce a third layer (the mesoderm) between these two layers, making them triploblastic.

Answer 2

Answer:

A germ layer is a primary layer of cells that forms during embryonic development.[1] The three germ layers in vertebrates are particularly pronounced; however, all eumetazoans (animals more complex than the sponge) produce two or three primary germ layers. Some animals, like cnidarians, produce two germ layers (the ectoderm and endoderm) making them diploblastic. Other animals such as chordates produce a third layer (the mesoderm) between these two layers, making them triploblastic. Germ layers eventually give rise to all of an animal’s tissues and organs through the process of organogenesis.
