To what kingdom does seaweed belong Animal Plant Fungi Protista Eubacteria?

Seaweed belongs to the kindom of planti because it's of corse a PLANT and if you new the kindoms a bit better then you would know that any living thing that creats it's own food NOT BY COOKING IT IN MICROWAVE OR OVEN OR KILLING IT is a plant Duh I'm 13 and i know that

Yes you are 13 but you obviously dont know how to spell course so go back to 8th grade you little moron.

The 13 year old kid is wrong. Seaweed or Algae have no formal taxonomic significance, so basically they belong to no kingdom. However, they are divided in two kingdoms. Cynobacteria or "blue-green algae" is placed in the kingdom Eubacteria. While, red and brown algae is placed in protists.

Just because a living thing can produce its own food (Photosynthesis and Chemosynthesis) doesn't mean it is a plant. Eubacteria, Archaebacteria and Protists all produce food through photosynthesis (except Eubacteria, it produces food by chemosynthesis and photosynthesis.)

I hope this help.

Too add to the second person who is correct i just wanted to point out that Blue-green Algae is not algae even though it is named after algae. You are correct about its kingdom though.
