What term refers to tiny organisms that are made of a single cell?

Explanation:
Bacteria are tiny, single-celled microorganisms. Each bacterium carries out all life processes within one cell, and they are typically microscopic. The other terms describe different ideas: organisms is any living thing (not necessarily single-celled); cells are the basic unit of life (not organisms themselves); microbiome refers to a community of microorganisms living together in a habitat. Since the prompt asks for a name for tiny organisms made of a single cell, bacteria is the best fit.
