- Confidence votes 54. Protists are different from bacteria and archaea as protists, that have nuclei and can be multicellular, as from bacteria and archaea, that has no nuclei and is unicellular.acteria are pr … okaryotic, and do not have nuclei. Also, protists are sort of like the miscellaneous category. There are plantlike cells (such as diatoms) and animal-like cells (such as ameoba). Bacteria and protists also have different shapes to their cells and different organelles.

Difference Between Protists and Bacteria Bacteria. The Bacteria are considered as unicellular prokaryotic organisms. Unlike eukaryotes, bacteria cells lack an organized nucleus, mitochondria, chloroplasts and other membrane bounded organelles. Bacterial cell has only a circular DNA, which does not associate with histone protein.Bacteria do not show sexual reproduction methods.nlike eukaryotes, bacteria cells lack an organized nucleus, mitochondria, chloroplasts and other membrane bounded organelles.

- Archaeans are single-celled creatures that join bacteria to make up a category of life called the Prokaryotes (pro-carry-oats). Prokaryotes' genetic material, or DNA, is not enclosed in a central cellular compartment called the nucleus. Bacteria and archaea are the only prokaryotes. All other life forms are Eukaryotes (you-carry-oats), creatures whose cells have nuclei.

What are the two major groups of prokaryotes? The Archaea are a group of prokaryotic, single-celled microorganisms. In this they are similar to bacteria but these two groups evolved differently, and are classified as different domains in the three-domain system.Originally these organisms were named archaebacteria.rchaea were originally described in extreme environments, but have since been found in all habitats and may contribute up to 20% of total biomass. These cells are particularly common in the oceans, and the archaea in plankton may be one of the most abundant groups of organisms on the planet.

- Eukaryotes can be found variously as single-celled organisms called protists, and as organized systems in multicellular organisms. The cells of all plants, animals and fungi are eukaryotes. The prokaryotes live on in the two major divisions of bacteria-the eubacteria and the archebacteria.aluable Lessons. Having established that Giardia occupies an important position in the transition from prokaryotes to eukaryotes, we have been interested in exploring aspects of its life history to see what we can learn about the early eukaryotes.

- The Protista Kingdom lies between the Monera Kingdom and the Plantae Kingdom; most protists are still single-celled like bacteria, but their cells are more complex. Like bacteria, not all protists are autotrophic; however, almost all protists that do engage in photosynthesis have some type of chlorophyll.

Difference Between Protists and Bacteria Protists vs Bacteria. According to common biological classification, protists are classified under Kingdom Protista, while Bacteria are classified under Kingdom Monera. Unlike the cells of other organisms (plants and animals), protists and bacteria cells have very low level of cell differentiation.Due to this reason, the cells of a single individual are morphologically and functionally similar, thus reduces its adaptations and development capacity.rotists vs Bacteria.

Diatoms Protozoa and algae are both protists. Protists are eukaryotic microorganisms, which belong to the kingdom Protista. There have been attempts to remove the kingdom from the taxonomy but it is still very much in use. The term protista was first used by Ernst Haeckel in 1866. Protists were traditionally subdivided into several groups based on similarities to the higher kingdoms: the unicellular animal-like protozoa, the plant-like protophyta (mostly unicellular algae), and the fungus-like slime molds and water molds.

- Archaebacteria --Prokaryotic, unicellular, nutrition by absorption (heterotrophic). This group of bacteria-like organisms live in harsh (high temperature, salinity, etc.) environments similar to that of ancient earth (hence the name). They cell wall structure is different than that of typical bacteria.

Archaea Domain Archaea are a group of microscopic organisms that were discovered in the early 1970s. Like bacteria, they are single-celled prokaryotes. Archaeans were originally thought to be bacteria until DNA analysis showed that they are different organisms.

Difference between Archaea and Bacteria Prokaryotes microorganisms can be further classified into three domains: eukarya, bacteria and archaea. This can become a bit confusing as these two are similar in looks and can often be confused based on look alone, though these are different from each other in many ways.

- There are three domains, two of which, Eubacteria and Archaea, are composed entirely of prokaryotic organisms; the third domain, Eucarya, encompasses all other (eukaryotic) life forms, including the single-cell and multicellular protists, as well as animals, green plants, and fungi.hoto by: Sebastian Kaulitzki. Bacteria are microscopic organisms that comprise the domain Eubacteria. A domain is the highest grouping of organisms, superseding the level of kingdom in the classical Linnaean system of biological classification.

Archaea & Bacteria: Similarities & Differences Archaea, bacteria, and eukarya form three distinct branches of the Tree of Life or the phylogenetic tree, which traces the evolutionary history of organisms and indicates common ancestors. Archaea used to be thought of as bacteria, though this is an erroneous classification. Archaea and bacteria are definitely both tiny, single-cell organisms, which cannot be seen by the naked human eye called microbes.

- Protists. Protists are single and multicellular organisms that are plant-like, animal-like and fungi-like. They evolved from bacteria and represent the intermediate step in the evolution of the other three kingdoms. There are 12 phyla in this kingdom, most of which live in water.

Protists vs. Prokaryotes What characteristics of protists differentiate them from bacteria? What do protists do that bacteria and archaea do not do? How do you think these differences have affected their spread? Physically, the cell structure of protists and prokaryotes differ. First, the external structures of prokaryotes consist of cell walls made of peptodoglycan. Protists do not have a cell wall, and instead have a semi-permeable plasma membrane in the form of a phospholipid bilayer.

What are Archaebacteria? Archae are microorganisms which explain the limits of life on earth. Archaebacteria are a type of prokaryotic unicellular organism with distinctive cell membranes belong to the kingdom “Archae” without a cell nucleus. Archae was first classified as a seperate group of prokaryotes in 1977.It is difficult to classify as they have similarities to normal bacteria and larger eukaryotes.rchaebacteria differ from cell wall and cell membrane as it contains a single layer of phospholipid which allows the archaebacteria to live in very limited resource environments. It acts like a parasite which do not harm or help the host.

- This group contains plant-like, animal-like, and fungus-like organisms. This grouping is not based on evolutionary relationships but is more a grouping of convenience — the protists are the eukaryotes that aren’t plants, animals, or fungi.here will likely be changes in this grouping as the science of classification progresses. The majority of organisms classified as protists are unicellular though there are a few multicellular organisms. For example, kelp (“seaweed”) is technically a protist even though it is multicellular.

You may be wondering why those protists are not classified in the Archaebacteria or Eubacteria kingdoms.

- Cells are divided into two main groups, based on whether they have a nucleus or not. Eukaryotes have a well-defined nucleus, while prokaryotes do not. Classified as prokaryotes, bacteria include two major groups: eubacteria, which are medically relevant bacteria, and archaeabacteria, the oldest living organisms. When people mention bacteria, they are usually referring to eubacteria, or any of their numerous subgroups.
