No! Bacteria (or bacterium if you're speaking of only one) are one-celled or unicellular microorganisms that don't have chlorophyll and don't have a distinct membrane-enclosed cell nucleus, like plant and animal cells do. Instead, the nuclear material--a single strand of DNA--is folded and clumped in the interior of the cell. Microorganisms that don't have a distinct nuclear membrane are called prokaryotic organisms. Bacteria are classified in the kingdom Monera, along with blue-green algae, which are also prokaryotic.
They're not aliens from another planet, in spite of the name! Protists are unicellular eukaryotic organisms: their cell nuclei are enclosed in membranes. They live in water (or watery tissues within the body, in the case of some diseases) and are classified in their own kingdom. You might have heard of some of these protists before: amoeba, euglena, paramecium, dinoflagellates, slime mold, and even most algae. Kingdom Protista seems to be the catch-all category of the cell world!
