Question

What do you understand by diploblasty ? Give one example of an organism which is diploblastic. ​

Answer 1

Answer:

Diploblastic animals have only two embryonic germ layers (ectoderm and endoderm). Cnidarians, such as jellyfish, coral and sea anemones, are examples

Answer 2

Diploblasty

• Diploblasty is the condition in which cells in an organism are arranged into two embryonic germ layer , an ectoderm and endoderm.

• Ectoderm is the external germ layer.

• Endoderm is the internal germ layer .

• In Diploblastic organisms there is also an undifferentiated layer known as the mesoglea , which is found between the ectoderm and the endoderm .

• Diploblasty is shown by lower organisms in the animal kingdom from, Phylum - Porifera to Phylum Ctenophora.

Note

• The other type of arrangement of germ layer is Triploblasty.

• In triploblasty a third germ layer known as the mesoderm is seen in between the ectoderm and entoderm.

• Triploblasty is shown by Higher organisms in the animal kingdom , from Phylum - Platyhelmintes to Phylum - Chordata .
