Gee. I guess there's a lot of money in that field right now. Now we have
genetically engineered algae that can get diabetes!
I've read about naturally occuring algae that lost the ability to
photosynthesize, and so are completely dependent on sugars they can get
out of their environment. They're called "leucophytes"; they have all the
internal structures that normal algae have (chloroplasts, in particular)
but no chlorophyll or other pigments.
