See the extract, In the higher forms of Sycons the radial tubes no longer arise as simple outgrowths of the whole sponge-wall, but rather as outgrowths of the endoderm into the mesoderm, which, together with the ectoderm, exhibits an indepen dent growth of its own; and this results in the formation of a thick investment, known as the cortex.

The formation of cortical substance is an advance in the organization of protozoans, giving them more consistency and a more definite or more persistent shape.
