Question:

Which of the following not started from Cnidarians?

Options:

1. Tissue level of Organisation
2. Radial symmetry
3. Diploblastic body plan
4. Presence of mesoderm

Solution:

Cnidarians, which include animals such as jellyfish, corals, and sea anemones, are diploblastic animals, meaning they have two germ layers (ectoderm and endoderm) and lack a mesoderm. They exhibit radial symmetry, have a tissue level of organization (where different cell types are organized into distinct tissues), and possess a diploblastic body plan (with two germ layers). However, they do not possess a mesoderm, which is the third germ layer found in triploblastic animals. Mesoderm gives rise to structures such as muscles, circulatory system, and internal organs in many animals, but it is not present in Cnidarians.
