State whether the following statement is true or false:
The animals belonging to phylum Nematoda contain only tissues and no real organs.

(TRUE) The statement is True.
Animals in the phylum Nematoda (also known as Nemathelminthes or roundworms) exhibit a tissue-organ level of body organization. While they possess a complete digestive tract (a significant evolutionary advancement),they lack complex,specialized organ systems found in higher phyla. Therefore,they are generally described as having a tissue-organ level of organization rather than a complex organ-system level.
