They differ in their evolution processes. Skip to content The world comprises of uncountable living organisms some of which are similar and some are different.
Protists are the genetically modified organisms that belong to the kingdom Protista. Bacteria are the organisms having a single cell with the simplest cell structure. They can have a spiral shape, rod shape, spherical or a chain like structure.
Bacteria lack a nucleus, mitochondria, chloroplasts and organelles. Protists can either be single-celled or multiple called. They contain a nucleus surrounded by a nuclear membrane. The DNA or genetic material of a bacteria is not surrounded by a protective membrane known as a nuclear membrane. Thus, they are termed as prokaryotes. The genetic material in protists is surrounded by the nuclear membrane along with chromosomes.
Therefore, protists are classified as eukaryotes. They maintain the food chain in the environment by a process of recycling nutrients. They are also found in the human gut and maintain health by producing vitamin K and vitamin B They are used in industries for making bread, alcohol , yoghurt and cheese. Protists are equally important for maintaining an equilibrium in the ecosystem. They are responsible for supplying oxygen which is necessary for breathing.
Bacteria and Protists are both important living organisms which compromise a major part of our surroundings. Though they have evolved from common ancestors , there are certain vital differences which show the process of evolution between both the organisms.
Protists have a highly evolved and well defined cell structure in comparison to Bacteria. Protists are only found in moist surroundings, while bacteria are found everywhere. Bacteria are single celled while protists can be single celled or multicellular.
Difference between bacteria and protists. Difference Between Similar Terms and Objects. MLA 8 P, Rachita. Name required. Email required. Mixotrophs are class of protists which possess plastids and also eat organisms, e. Protists reproduce by binary fission or multiple fission, some protists reproduce sexually but very few. Free-living protists live in watery areas. The conclusion of the above discussion is that Bacteria and Protists are both microscopic organisms but belong to different kingdoms and have their own characteristics features.

Exceptions to this universality include the fact that some bacteria use the sequence UAG to code for pyrrolysine rather than a stop codon, which is how it is used in other organisms.
Nonetheless, for the most part, the code is a remarkable similarity between bacteria and protists. Again, protists and bacteria share these similarities with all other known forms of life. The structure of the ribosome differs somewhat between bacteria and eukaryotes like the protists. This difference is an important one, too, because some antibiotics kill bacteria by making use of differences between bacterial and eukaryotic ribosomes. Both bacteria and protists have cell membranes made of chemicals called phospholipids.
A phospholipid in a bacterium or a protist has a water-soluble group at one end and a water-insoluble tail at the other, so the cell membranes of bacteria and protists are constructed from a bilayer of phospholipids.
