H. v. wilson worked with sponges to gain some insight into exactly what was responsible for holding adjacent cells together. he exposed two species of differently pigmented sponges to a chemical that disrupted the cell-cell interaction (cell junctions), and the cells of the sponges dissociated. wilson then mixed the cells of the two species and removed the chemical that caused the cells to dissociate. wilson found that the sponges reassembled into two separate species. the cells from one species did not interact or form associations with the cells of the other species. how do you explain the results of wilson's experiments?
