*A green sea slug appears to be part animal, part plant. It’s the first critter discovered to produce the plant pigment chlorophyll.
The sneaky slugs seem to have stolen the genes that enable this skill from algae that they’ve eaten. With their contraband genes, the slugs can carry out photosynthesis — the process plants use to convert sunlight into energy*
Story from msnbc..
I think the implication here is that one of their ancestors hijacked the algal genes, and now they’re part of the slug’s own genome.
Animals that capture chloroplasts or algae and farm them internally are nothing new - this sounds like a case where the animal has hacked its own genes.
Yep, the same way we develop a helpful group of intestinal fauna and flora. We aren’t born with them, and can’t produce them, we just pick them up along the way and symbiosis has developed.
The artical is suggesting that these slugs actually ahve the production of chlorophyll as an inate ability.
Yes, in some cases (jellyfish, I think), the organism captures and absorbs single-celled algae - the algae use water, sunlight and the host organism’s waste products to produce sugars - the host organism attacks the algae (with enzymes or something), causing them to leak sugars, but without actually killing them.
