Define the following:

Germ layers

Answer 1

Germ layers:

1. Some animals have three different types of germ layers. As a result, these creatures are known as triploblastic animals.
2. Because certain animals only have two types of germ layers, they are known as diploblastic animals.
3. Ctenophora, Cnidaria, and Porifera are examples of diploblastic creatures.
4. Throughout embryonic development, germ layers coordinate tissues and assist the creation of tissues and organs.
5. First, the ectoderm and endoderm layers are formed. The mesodermal layer is then formed.
6. Heart, muscle, and connective tissue development are aided by mesodermal layers.
7. The body cavity emerged from the mesodermal layer.
