Document Summary
Aka: solar powered opisthobranchs: they are green because they perform photosynthesis, animals that photosynthesize. It is not just one species that does this, there are a number of species: eats chloroplasts and keeps them, the plant becomes photosynthetically active by using the chloroplast. This marine snail elysia chlorotica (cid:498)kidnaps(cid:499) chloroplast by eating algae (cid:498)scientists have shown that once a young slug has slurped its first chloroplast meal from rest of its life. All it has to do is sunbathe. (cid:499) one of its few favored species of vaucheria algae, the slug does not have to eat again for the: derives it energy by eating chloroplasts. They found in the marine slugs: 101 chloroplast-encoded gene sequences, 52 nuclear-encoded genes, from the chloroplast donor, vaucheria litorea. The symbiotic chloroplasts are translationally active: genes are transcribed and translated. Marine slugs control the chloroplasts on their own similar to what happens in plants. Functional algal genes have been transferred into the slug genome.
