algae).  Actually just about every Eukaryote, including us, has that sort of
mix since mitochondria are also believed to be derived from bacteria that
struck up a symbiotic relationship with its host.  If you are thinking of
some other feature of red algae please let me know because I am forgetting
it or ignorant of it.

fern and a Selaginella that does the same thing are pretty fascinating
actually, but I digress.  Bacteria are the all time champions though
(surviving outside in outer space and coming back to life after 300 million
years in amber is hard to beat!).

Hi Kyle;
I understand pretty much everything (including us!) are really just big
bacterial colonies or made from parts thereof. But as you point
out there's a big difference between the green plant-like alga
and the little buggers in kingdom Monera. The latter are very
sensitive to H202, the former are not, which I find interesting.

Peroxide seems to kill lower life forms first, and that there
should be such a difference in the sensitivity to it among
two distinct gorups of alga gives one the impression - however
true or untrue - that they're a lower, ie, less evolved form of
life.

I have a reserrection fern. It's fun to hydrate it, then
ignore it again. I keep it outside. I can't even tell if it's
alive - it just unfurls when it's wet, then goes back
into a ball when it dries out.
