The sea slug Elysia chlorotica that lives on the East coast of Canada and the United States “steals” chloroplasts from algae, stores them in its body, and uses photosynthesis to produce energy that it can live from without further feeding. This is quite remarkable, as it was assumed until now that chloroplasts need the cell nucleus of the algae to function properly. While this is apparently not the case, researchers believe that this might provide a new opportunity to develop solar panels based on artificial photosynthesis for the production of energy.
