After a few hours, the cells of each sponge would re-aggregate and form three new sponges.
We can reach this answer because:
- The sponge is a multicellular organism with little cell differentiation.
- The surface of sponge cells has a group of glycoproteins, which allow communication between all the cells in a sponge.
- These proteins are transmembrane receptors, which emit signals responsible for the cell adhesion process.
- The cell adhesion process allows the cells in a sponge to regroup if they are separated.
In this case, if three sponges had their composition sieved and mixed, the glycoproteins of their cells would allow each sponge to be remade, as there would be communication and a regrouping of the cells of each sponge.
