Protists vs Bacteria


Understanding the various microorganisms might confuse you especially they were involved in different biological classifications. In this article, the distinction between protists and bacteria will be explained as basic but substantial as possible. The protists belong to the Kingdom Protista whereas the bacteria belongs to the Kingdom Monera.

  Protists Bacteria
Cell Multicellular Single celled
Residence Moist surroundings Practically everywhere
Food Making Heterotrophs  Autotrophic/Heterotrophic
Nucleus classification Eukaryotic  Cells Prokaryotic Cells
Kingdom Protista Monera
Cytoskeleton Present Absent
Mitochondria Present Absent

Protists are described as unicellular having nucleus, nuclear membrane, chloroplast, mitochondria, and several organelles. They usually resemble eukaryotes cells. There are two ways on how these microorganisms feed themselves. One of which is they ingest the food to their cells by means of engulfing the food particles. Meanwhile, some protists have photosynthesis features in which they can create their own food such as blue-green algae. Moreover, the Kingdom Protista is subdivided into other kingdoms such as slime moulds, protozoa, and protophyta.

Another unicellular microorganism aside from the protists referred to the bacteria. Unlike the protists, these cells do not contain mitochondria, nucleus, nuclear membrane, or chloroplasts. They do not assimilate sexual production rather they produce themselves through asexual means. Some bacteria possess flagella which enable them to move. Some of the typical examples of bacteria include bacilli, spirilla, cocci, and vibrios. Bacteria feed themselves by performing the heterotrophic or autotrophic method.
