Sponge is categorized in the subkingdom Parazoa because they lack true tissues and organs, which distinguishes them from other more complex multicellular organisms. Parazoa includes organisms that exhibit a simple body plan and are primarily composed of specialized cells that perform specific functions without forming organized tissues. Additionally, sponges exhibit a unique cellular structure that allows them to filter feed and thrive in aquatic environments, highlighting their evolutionary simplicity.

Porifera (pōrĭf'ərə) [Lat.,=pore bearer], animal phylum consisting of the organisms commonly called sponge. It is the only phylum of the animal subkingdom Parazoa and represents the least evolutionarily advanced group of the animal kingdom. All adult sponges are sessile (nonmotile), and nearly all are marine; there are four families of freshwater sponges. Sponges are subdivided into three classes.
If a sponge is placed through a sieve, the sponge will likely get stuck in the sieve's mesh due to its size and inability to compress easily like a liquid or fine particles. It may require manipulation or cutting to remove the sponge from the sieve.
A sponge stick is reportedly something used by ancient Romans. In lieu of toilet paper, they used a sponge placed on a stick.

Subkingdom algae is the condensed version of Kingdom Protista. It contains organisms such as seaweed, rockweed, Phaeates, and some types of moss.
The Animal Kingdom or Kingdom Animalia
The seed pods have a plastic shell, inside the shell is a sponge that your seeds are placed in.
Protozoa are unicellular organisms with animal-like characteristics, such as the ability to move and ingest food. Parazoa, on the other hand, are multicellular organisms that lack true tissues and organs. They include sponges, which are filter-feeding animals without distinct symmetry.
