Which of the following animals have scattered cells with cell–tissue grade organisation :Sponges have a cellular level of organisation: their cells are loosely aggregated and do not form true tissues.
In cnidarians such as Hydra, the cells performing the same function are arranged into tissues (tissue level of organisation), though many cells are still scattered (e.g. interstitial cells, nerve net).
Liver fluke and Ascaris have the organ (and organ system) level of organisation.
