Diffusion of oxygen through the mesoglea of the sea anemone calliactis parasitica


Journal of Experimental Biology 107: 181-188
Diffusion of oxygen through the mesoglea of the sea anemone calliactis parasitica
The diffusion of O2 through preparations of the mesogloea of C. parasitica (Couch) was measured with a custom-built diffusion cell and an O2 microelectrode. The mean value for Fick's diffusion coefficient was 7.29 .times. 10-6 cm2 s-1 and that for Krogh's diffusion constant 10.00 .times. 10-6 cm3 O2 per min per cm2 area and cm thickness at a pressure difference of 1 atm, at 25.degree. C. Comparison with the rather few values in the literature for O2 diffusion through biological materials indicates that mesogloea is similar to connective tissue. The mesogloea of Calliactis seems to present a fairly significant barrier to the diffusion of O2 between the 2 cell layers. This is discussed in relation to the route whereby the endoderm obtains its O2.
