I think my point was it is not an animal therefore a plant. Even though they are not exactly the same as land plants they are certainly not animals. I'm pretty sure that all land plants evolved from green algae or so the text states anyway. Scientist love to debate the finer points and change things around when something does not fit perfectly into one category. Anyway....
