Single-celled organisms have chemical memory, which you can demonstrate by experiment, but I think I'd only consider some single celled organisms to have consciousness. Single-celled covers everything from archaebacteria to amoeba, afterall.
My definition I'm not so sure of, but I think it involves memory -- taking an experience and changing future behaviour as a result.
