Huang · Answer 1

a. These cells have formed mesoglea.

Explanation:

Mesoglea is the amorphous, acellular layer in cnidarians that separates the ectodrerm and the endoderm. The mesoglea is referred to as the hydrostatic skeleton in cnidarians such as jelly fish. The mesoglea, although supplied with muscles and nerves, is completely composed of water.
