Someone else has already pointed out this excludes rare 
saprophytic/parasitic forms, but it also _includes_ a large group of 
prokaryotes.  I've never objected to the term 'blue green _algae_', as 
these organisms do very similar things to eukaryotic algae, but now you've 
got the plant kingdom stradling the divide between eu- and prokaryotes.

I think I'll stick with a definition I heard a while ago -

"If it's green, it's a plant" :-)
