Answer:
The coelom is covered by mesoderm layer but the pseudocoelomate are not covered
Explanation:
The multicellular organism is made of three layers: the ectoderm, endoderm and mesoderm. The organism which possesses the true cavity is known as the coelomates and their coelom is covered by the mesoderm.
The organisms which do not possess the true cavity but cavity-like structure are called pseudocoelomates and their coelom is known as the false or pseudocoelom. The pseudocoelomates are not fully covered by the mesodermal layer.
Thus, The coelom is covered by mesoderm layer but the pseudocoelomate are not covered
Answer: coelom
Explanation: Only a coelom is fully lined with mesoderm tissue. A coelom is formed from mesoderm tissue, whereas a pseudocoelom is formed from mesoderm and endoderm and is not fully lined with mesoderm. Read about body cavities.
