Tripoblastic animals have three germ layers
ectoderm
endoderm
mesoderm
ectoderm- forms the brain and nervous system, epidermis and associated structures (skin, hair, nails)
endoderm- forms embryonic gut, inner lining of the digestive tract, inner lining of the respiratory tract and glands including the liver and pancreas
mesoderm- forms the notochord, and somites which includes muscle, outer covering of internal organs, excretory system and gonands, as well as mesenchyme (loose migratory cells) like the dermis (inner skin layer) the circulatory system (heart and blood vessels) and bones and cartilage
Happy studying :D
The endoderm of the gastrula turns into internal organs such as the liver and pancreas, and into the lining of some systems.
No, muscle tissue is not formed by the endoderm. Muscle tissue is derived from the mesoderm layer during embryonic development. The endoderm gives rise to the lining of many internal organs such as the gastrointestinal tract and respiratory system.
They have two layers the endoderm and ectoderm.
The endoderm and ectoderm
Endoderm is formed during gastrulation, which is the process by which the single-layered blastula is transformed into a trilaminar structure. The endoderm forms the innermost layer of cells and gives rise to the lining of the digestive tract and associated organs, such as the liver and pancreas.

The endoderm.
endoderm
The three germ layers of a gastrula are the ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer). These layers give rise to different tissues and organs in the developing embryo through a process known as gastrulation.
Prussian embryologist Robert Remak coined the term "endoderm" in 1835. The endoderm is the innermost of the three primary germ layers of an embryo. The endoderm may also be called the hypoblast.
no
endoderm, mesoderm, then ectoderm
The endoderm of the gastrula turns into internal organs such as the liver and pancreas, and into the lining of some systems.
No, muscle tissue is not formed by the endoderm. Muscle tissue is derived from the mesoderm layer during embryonic development. The endoderm gives rise to the lining of many internal organs such as the gastrointestinal tract and respiratory system.

it is the endoderm
