sponges have cellular level organisation meaning that their cells are specialized so that different cells perform different functions
tissues, organs, and organ system
Sponges
Sponges are at the tissue level of organization. They lack organs and organ systems, instead having specialized cells grouped together to perform specific functions.
Cnidaria or poricnid
The highest level of organization a sponge has are Cells.
well a big choad
Sponges are the most primitive animals, therefore, they have the lowest structural organization. Hope this helps!

Cellular level of organisation means when the animal body formed by many cells but the cell show no-coordination to form a tissue . Eg- sponges
The organism. The levels of organization of an individual from smallest to greatest are: atoms, molecules, cells, tissues, organs, organ systems, and organism. Not all organisms have all levels of organization, such a bacteria, protists, sponges, and more.
Sponges are less complex because they are just made of individual cells. There is no level of organization past cells in sponges. Cnidarians, on the other hand, have tissues, a higher level of organization. Tissues allow for some forms, like box jelly fish, to have eyes (this is just one of many advantages of tissues). Cnidarians' level of organization stops there though, they have no organs (heart, brain, etc.).
Pinacoderm and choanoderm in sponges are not considered true tissues because they lack the level of organization and specialization found in true tissues. The pinacoderm serves as a protective outer layer, while the choanoderm consists of flagellated cells that aid in water circulation and feeding, but both layers are not composed of tightly bound cells with defined functions. Instead, they retain a more simple, cellular organization characteristic of the primitive body plan of sponges, which do not have the complex tissue structures seen in more advanced animals.
