Genome of Photosynthetic Animals Decoded

Some sea slugs take up chloroplasts into their cells from the algae that they consume. These chloroplasts retain their ability to perform photosynthesis within the animal cells for several months and provide the sea slugs with nutrition. Genome analysis of photosynthetic sea slugs has revealed that chloroplast acquisition occurs without gene transfer.
