Why are prokaryotes not monophyletic?
Protists are a paraphyletic group because animals, fungi, and plants are the crown groups evolved from different lineages of the protists. They aren't included in the same group as protists taxonomically. This explains why the cladists consider the protist a paraphyletic group.
A human cell that does not have a nucleus?
A prokaryote cell doesn't have a true nucleus. See: http://wiki.biomine.skelleftea.se/wiki/index.php/Prokaryote_versus_eukaryote for an explanation of the differences between eukaryotes, cells with a true nucleus, and prokaryotes.
Why animal-like protists are not placed in the animal kingdom?
According to new system of classification as given by Whittaker 1969 unicellular animals are included in a seprated kingdom known as protista and or known as protozoans i.e. single cell. The animal kingdom consists of multicellular organisms. The multicellular organisms are called metazoans and their cells are capable of performing all the essential activities of life.
Is bacteria the same as a microbe?
They are merely definitions, with one of them encompassing the other. A microorganism or microbe is an organism that is microscopic (usually too small to be seen by the naked human eye). Microorganisms include bacteria, fungi, archaea, and protists; microscopic plants (called green algae); and animals such as plankton, the planarian and the amoeba.Therefore, it would be similar to asking is a Pine tree the same thing as a tree?
What are the characteristic of the organisms belonging to kingdom monera?
The kingdom Monera is constituted by bacteria, these live forms were the first organism which appeared on Earth. Bacteria characterize for being unicellular live forms, which implies that they are completely asexual organisms and the only way for them to "procreate" is by dividing themselves in two genetically equal bacteria. This process is called mitosis, all the unicellular organisms and cells (except sexual cells, ovules and spermatozoa) copy their DNA and split in "mother" and "child". Some bacteria enter inside another creature's body in order to find food, protection,... and avoid their death. This can cause diseases in animals and human beings, sometimes killing the host. However, bacteria are used in Medicine to create antibiotics and vaccines. Also they can ferment certain substances, which we use like: alcohol (medicinal alcohol and the one people drink), yeast, and they rot the corpses which implies an important role in the ecosystem because the nutrients will be transferred to the plants, from the plants to herbivorous,... always moving around among the life forms in the planet.
What is difference between eukaryotes and prokaryotes?
Prokaryotes do not have a nucleus included in their cells. Eukaryotes do have a nucleus included in their cells. And prokaryotes are more simple, it is the simplest, but eukaryotes are very complicated. And prokaryotes are single cells, but most of the eukaryotes make a big organism like plants and animals.Eukaryotes have membranes around their organalles
Why are prokaryotes not monophyletic?
Protists are a paraphyletic group because animals, fungi, and plants are the crown groups evolved from different lineages of the protists. They aren't included in the same group as protists taxonomically. This explains why the cladists consider the protist a paraphyletic group.
What is the difference between the kingdom prokaryotae and the kingdom plantae?
protocista are eukaryotic organisms which are not included elsweher where as prokaryotes are things like bacteria and cyanobacteria
How do protists differ from archaebacteria and eubacteria?
Sorry to be rude, but isn't that obvious? Archaebacteria and Eubacteria are both bacteria, just in a different form. Bacteria are not protists because they lack parts just to be a cell. They are alive but are not included in the Protista family because they lack a nucleus, lysosomes, and so on.
What domains of classification do prokaryotes include?
Unicellular prokaryotic organisms are actually broken up into the Bacteria and Archaea domains. The Bacteria domain has several shapes, and the Archaea domain generally resembles the bacteria domain.
A human cell that does not have a nucleus?
A prokaryote cell doesn't have a true nucleus. See: http://wiki.biomine.skelleftea.se/wiki/index.php/Prokaryote_versus_eukaryote for an explanation of the differences between eukaryotes, cells with a true nucleus, and prokaryotes.
What does archaezoa means?
The word archezoa was a kingdom that Thomas Cavalier-Smith for eukaryotes. Included were the eukaryotes that diverged before the origin of mitochondria.
What was the only one organism which is not included either in prokaryote or in eukaryote?
Prokaryotes are the organisms that do not have nuclei. The word itself says pro = primitive; karyon = nucleus. This means that the DNA is not surrounded by a membrane.
The genetic material of which kind of cells is included in a single circular molecule of DNA devoid of any histone proteins?
You must have Dr. Gay, or they use standard tests! The only idea I have is BACTERIA because all eukaryotes have histones, so that would rule out plants and animals.
Are protists monophyletic polyphyletic or paraphyletic?
Protists are a paraphyletic group because animals, fungi, and plants are the crown groups evolved from different lineages of the protists. They aren't included in the same group as protists taxonomically. This explains why the cladists consider the protist a paraphyletic group.
What does a Monera cell do?
Monera is an obsolete name for the taxonomic group that once included bacteria and archaea (prokaryotes). Now it is no longer used. The organisms that that term refers to are incredibly diverse, and the cells themselves grow and reproduce, as all cells do!
Why is cyanobacteria bacteria not algae?
At one time cyanobacteria were called blue-green algae and were included with the algae. However, like bacteria and unlike algae, cyanobacteria are prokaryotes, meaning that they do not have a nucleus. For this reason they were removed from the algae (which are eukaryotes) and put into the bacteria, with all the other prokaryotes.
