Current Question (ID: 13534)

Question:

Which one of the following statements is incorrect?

Options:

1. Mesoglea is present in between ectoderm and endoderm in Obelia
2. Asterias exhibits radial symmetry
3. Fasciola is a pseudocoelomate animal
4. Taenia is a triploblastic animal

Solution:

The statement, Fasciola is a pseudocoelomate animals, is incorrect as it does not possess body cavity hence, it is an acoelomate. Mesoglea is an undifferentiated layer and is a characteristic of diploblastic and triploblastic animals present along with ectoderm and endoderm. Symmetry in which the body can be divided into two equal identical halves from any plane passing through the central axis, as shown by Asterias, is called radial symmetry. Taenia is a triploblastic animal, it possesses three germinal layers, i.e, ectoderm, endoderm and mesoderm.
