Answer:
The correct answer will be option- true
Step-by-step explanation:
A germ layer is a layer formed by the group of cells during the development of the embryo in animals.
The germ layer interacts with each other and through the process of organogenesis forms different organs of the organisms. The organism having two germ layers- ectoderm and endoderm are called diploblastic and three germ layers called triploblastic as they posses mesoderm.
The mesoderm layer in animals allows the organism to form the coelom, its organs and other organs like urogenital organs, connective tissue, skeletal muscle and the heart.
Since the mesoderm is involved in the formation of the heart, therefore, true is the correct answer.
