Cnidarians have a close relationship with unicellular photosynthetic partners.
The relationship is widespread and occurs in many shallow-water cnidarians.
The photosynthetic protists grow inside the living cells of the gastroderm.
The protist takes the CO2 and metabolic wastes produced by cnidarians to manufacture oxygen and other organic compounds.
