in what ways are protists alike to bacteria?
491626
Both being unicellular (no matter what anybody said), and generally autotrophic organisms... All protists are unicellular, and not all algae belong to Regnum Protista... Place of algae in Whittaker's 5 Regnums is not well explained, and multicellular algae belong to Regnum Plantae... If someone has better idea where to classify them they could make a career out of it...\nBut remember, most people still divide all the organisms into 2 Regnums: plants and animals...

Kelp is a great example of a multicellular algae (which is protist), like the "kelp forests" in Alaska.  Check it out.\n\nhttp://www.oceanlight.com/html/kelp.html

Prokaryotic cells are cells associated with Bacteria.  Eukaryotic cells are found in Plants and Animals.

Bacteria are prokaryotic organisms. They are mostly unicellular, and they have no nucleus and other cell structures.\n\nProtists and Fungi, on the other hand, are eukaryotes, which are unicellular or multicellular organisms that have a nucleus and complex structures like mitochondria and chloroplasts.\n\nfor more details, go to an encyclopedia website like http://www.wikipedia.org

A bacterium is a microscopic unicellular organism with a simple cell structure, they procreate by fission, that is splitting and sharing DNA.\n\nA virus is a submicroscopic parasite which invades living cells, including bacteria, and hijacks the cell's systems to force the cell to make copies of the virus.

Prokaryotes (from Old Greek pro- before + karyon nut or kernel, referring to the cell nucleus, + suffix -otos, pl. -otes; also spelled "procaryotes") are organisms without a cell nucleus (= karyon), or indeed any other membrane-bound organelles, in most cases unicellular (in rare cases, multicellular). This set of characteristics is distinct from eukaryotes (also spelled "eucaryotes"), organisms that have cell nuclei and may be variously unicellular or multicellular. The difference between the structure of prokaryotes and eukaryotes is so great that it is considered to be the most important distinction among groups of organisms. Most prokaryotes are bacteria, and the two terms are often treated as synonyms. However, Woese has proposed dividing prokaryotes into the Bacteria and Archaea (originally Eubacteria and Archaebacteria) because of the significant genetic differences between the two. This arrangement of Eukaryota, Bacteria, and Archaea is called the three-domain system. This replaces the two-empire system.\n\nhttp://en.wikipedia.org/wiki/Prokaryote\n\n\nA eukaryote (IPA: [juːˌkarɪəʊt]), also spelled eucaryote, is an organism with a complex cell or cells, in which the genetic material is organized into membrane-bound nucleus/nuclei. Eukaryotes comprise animals, plants, and fungi—which are mostly multicellular—as well as various other groups that are collectively classified as protists (many of which are unicellular). In contrast, prokaryotes are organisms, such as bacteria, that lack nuclei and other complex cell structures. Eukaryotes share a common origin, and are often treated formally as a superkingdom, empire, or domain. The name comes from the Greek ευ, meaning good, and κάρυον, meaning nut, in reference to the cell nucleus).\n\nhttp://en.wikipedia.org/wiki/Eukaryote\n\nMORE STUFF ON LINKS

Protozoa (in Greek protos = first and zoon = animal) are single-celled eukaryotes (organisms with nuclei) that show some characteristics usually associated with animals, most notably mobility and heterotrophy. They are often grouped in the kingdom Protista together with the plant-like algae. In some newer schemes, however, most algae are classified in the kingdoms Plantae and Chromista, and in such cases the remaining forms may be classified as a kingdom Protozoa. The name is misleading, since they are not animals.\n\nProtozoa have traditionally been divided on the basis of locomotion, although this is no longer believed to represent genuine relationships:\n\n    * Flagellates\n    * Amoeboids\n    * Sporozoans: Apicomplexa, Myxozoa, Microsporidia\n    * Ciliates\n\nMost protozoans are too small to be seen with the naked eye - most are around 0.01-0.05 mm, although forms up to 0.5 mm are still fairly common - but can easily be found under a microscope. Protozoa are ubiquitous throughout aqueous environments and the soil, and play an important role in their ecology. A few are also important parasites.

In my biology class we were taught they are divided into 3 groups based on nutrition.  Protozoa, algae, and fungus like protists.  Protozoa are animal like in that they are heterotrophs.  Algae are autotrophs.  Protozoa are further classified by mobility (cilia, flagella, or sporozoa)

No, not directly.  Bacteria are of the order of single celled organisms called prokaryotes, we are multicellular organisms of the order eukaryote.  We share basic similarities such as DNA, RNA, certain cell makeup but our genetic orders split into two different directions at a very early stage.  The genetic relationship stopped there.\n\nWe do share a symbiotic relationship with bacteria in our bodies and the world around us if that's what you mean.  We rely on bacteria to help break down food and control digestion.  Without that relationship we'd die.

I think that referrs to the computur programs that mimic biological entities.\n\nFor example, programming many small robots to behave like ants is one (source 1).\n\nOr a computer program that models behavior of bacteria or another single celled organism. (source 2)\n\nIt might help to know what context it was written in, or where you hear it used.

I would imagine something in the microbe department. Like a paramecium or ameba.

Plant-like protists like algae, seaweed, and kelp for instance all play an important role in the marine food chain. Cyanobacteria, from which later plant-like protist life stemmed did help to oxygenate the atmosphere but phytoplankton, which is this plant-like protist life, forms the food base of the marine food chain according to my sources.

The protist needs to maintain homeostasis, the balance in the body, in order to live. Diffusion and Osmosis acheive this by allowing nutrientrs to come in and wastes to leave.

There are a number of examples in which prokaryotic organisms coalesce into multicellular structures. One of those examples are in a group of bacteria called myxobacteria. In this case, myxobacteria form what's called fruiting bodies as part of their life cycle (see the link below for a picture of a fruiting body).

u must be knowing that all organisms are classified into five kingdoms-monera,protista,anemalia,fungi and alge.\n\nthe MONERA phlum[group] consists of bacteria which are prokaryotic in nature -i.e, the cell doesnot have membrane bound organneles or nucleus.\n\nthe Protista group consists of organisms that are eukaryotic in nature-that is they have well defined organneles.\nthis is one reason that bacteria is kept in two separate groups.

There are only a handful becasue more antibiotics attack prokaryotic cellular structures, such as the prokaryotic ribosome, but protozoa are eukaryotic. Examples that are used inlcudeamphotericin B, metronidazole, pentamidine and tinidazole
