Which of the following plants most commonly grow in water?

I just had a battle with one other person and lost big time. I don’t think she missed a question.Haven’t won any battles yet.

Algae are not plants. They belong to kingdom Protoctista, not Plantae.

way to easy!

Frances, never seen black before but I can confirm there is red right in my hometown, growing in a lake and turn visible red around Oct-Nov, a pretty famous tourist attraction

Angela , I'm fairly sure algae is black and red as well.

That was interesting. I wonder if all algae is green?
