Re:Cotylodons and another question

Tom posed a question:
"If you want a question: what is the difference between Chara and Riccia?
Why
is one an "alga" and the other a "plant". Chara looks like a whorled stem
plant with internodal development, Riccia look more like algae than this
algae does."

Go here to get an idea of how complex the answer might be:
