Answer:

Protists and bacteria differ mostly in their cellular structure. Prokaryotes are creatures that lack a nuclear membrane around their genetic material (DNA), such as bacteria. On the other hand, protists are eukaryotic (genetic material enclosed by a nuclear membrane).

Step-by-step explanation:

Protists and bacteria are both often found to be single-celled creatures, yet they are extremely different from one another in almost every other way. Protists are creatures that belong to the Eucarya domain, like humans, and have internal compartments, a cytoskeleton, and many RNA polymerases in their cells. The size of eucaryal cells ranges from 10 to 100 microns (millionths of a meter). There are two types of bacteria: Eubacteria and Archaea, which are almost as unlike from one another as they are from Eucarya. Bacterial cells generally have a diameter of 0.5 to 5 microns. The simplest way to distinguish between them is based on size and whether or not they have nuclei; protists have one (or more), whereas bacteria don't. Finding their gene sequences—in particular, the sequences for ribosomal RNA, which is the most reliable method to categorize organisms—is a more accurate technique to separate them.

Answer:

Bacteria and protists are unicellular organisms. The difference lies in the type of cells they have. Bacteria are placed in the kingdom Monera and have a prokaryotic cell, whereas protists are placed in the kingdom Protista and have a eukaryotic cell.
