Question

Write in detail about Germ layers.

Answer 1

Hi buddy
A germ layer is a group of cells in an embryo that interact with each other as the embryo develops and contribute to the formation of all organs and tissues. All animals, except perhaps sponges, form two or three germ layers. The germ layers develop early in embryonic life, through the process of gastrulation. During gastrulation, a hollow cluster of cells called a blastula reorganizes into two primary germ layers: an inner layer, called endoderm, and an outer layer, called ectoderm. Diploblastic organisms have only the two primary germ layers; these organisms characteristically have multiple symmetrical body axes (radial symmetry), as is true of jellyfish, sea anemones, and the rest of the phylum Cnidaria. All other animals are triploblastic, as endoderm and ectoderm interact to produce a third germ layer, called mesoderm. Together, the three germ layers will give rise to every organ in the body, from skin and hair to the digestive tract.

A germ layer is a collection of cells, formed during animal embryogenesis.

Germ layers are only really pronounced in the vertebrates.

However, all animals more complex than sponges (eumetazoans and agnotozoans) produce two or three primary tissue layers (sometimes called primary germ layers).

Animals with radial symmetry, like cnidarians, produce two called ectoderm and endoderm, making them diploblastic.

Animals with bilateral symmetry produce a third layer in-between called mesoderm, making them triploblastic.

Germ layers will eventually give rise to all of an animal’s tissues and organs through a process called organogenesis.
