protista

Neither plant, animal

Protista is a biological kingdom comprising single-celled organisms that don't fit neatly into the plant, animal, or fungus categories—amoebas, algae, paramecia, and similar microorganisms.

The grouping is taxonomically contested since its members share few characteristics beyond being eukaryotic and not belonging elsewhere.
