Q. Mesoderm is present between Ectoderm and Endoderm in these animals are
Solution:
Solution:
Triploblastic organisms form all three primary germ layers — endoderm, ectoderm and mesoderm — during the gastrulation of the blastula. Mesoderm development is the characteristic feature in triploblastic animals. Mesodermal cells differentiate through the interactions of both ectodermal and endodermal cells. Coelom is developed from the mesoderm. Inside the coelom, freely moving organs are formed, providing protection against shocks by fluid cushions. These organs can grow and develop without the aid of the body wall. Mesoderm forms muscle, bone, connective tissues, circulatory system, notochord, etc. Other than that, endoderm develops into lungs, stomach, colon, liver, urinary bladder, etc. Ectoderm develops into epidermis, hair, eye lens, brain, spinal cord, etc. All animals from flatworms to human are triploblastic.
