The kingdom with only unicellular organisms is?

There is no single kingdom that is unicellular. All prokaryotes (organisms with no cell nucleus) are unicellular, and they belong to two domains, bacteria and archaea. Eukaryotes, or organisms with a cell nucleus, are divided into four kingdoms, plants, fungi, animals, and protists (although recently scientists began to reclassify protists into multiple separate kingdoms). In each of the fungi and protist kingdoms, there are a variety of members that are unicellular, and also some members that are multicellular. Animals and plants are always multicellular (except possibly one animal group called Myxozoa).


The largest group into which an organism can be classified?

According to taxonomic hierarchies (taxa), the major classification group is called "superkingdom", followed by "kingdom", "suprakingdom" and "domains". Superkingdom is a taxa with only use for a better classification, not a natural classification, it makes it easier to group organisms. The largets group is superkingdom Prokarya, the one concerned with bacterias, followed by kingdom fungi.


How are organisms in the domain of eukarya different from those in the domain archaea?

Domain Archaea is made of the oldest known organisms, most use chemiosynthesis (inorganic elements) to make energy and are found in more hostile environments (extremeophiles) and are build on the cellular level to survive in them and are similar to Domain Prokaryota. Domain Prokaryota organisms have no membrane bound organelles (chloroplasts, mitochondria, nucleus, ect.), their only genetic code is made of RNA and plasmids, they have a cell wall, are single celled, and move by cillia and flagella. Domain Eucaryota are the most complex and diverse of the three domains. They have DNA as their primary genetic code, membrane bound organelles, and are equipped with a wide array of organelles for specific tissue and organ functions, but some function as single celled organisms.


What organisms are least related to humans?

Very hard to say, but I suspect the archaebacteria are the least related to all other organisms (not just humans) as their common ancestor with other organisms is only shortly after the origin of life on earth. They are so distant that they even use a few amino acids in some of their proteins that no other organism today uses!


What are 3 of the IT infrastructure domains affected by internal use only data classifications?

Three IT infrastructure domains affected by internal use only data classifications include network security, access controls, and data storage. Network security measures need to be implemented to prevent unauthorized access to the data, access controls should be set up to restrict access to only authorized personnel, and data storage protocols should ensure that the data is stored securely and only accessible to authorized users.

Does unicellular means having more than one cell?

No, unicellular means an organism is made up of only one cell. Organisms that are unicellular, such as bacteria and yeast, are complete individuals composed of a single cell that carries out all functions necessary for life.

What is the difference between a microorganism and unicellular organism?

A microorganism is a tiny organism that can be single-celled or multi-celled, while a unicellular organism is an organism that is composed of only one cell. Therefore, all unicellular organisms are microorganisms, but not all microorganisms are unicellular.


Can you put unicellular in a complex sentence?

Not all the unicellular organisms have Ribosomes, but most of them Do.Dna Is an integral part of multicellular organisms, but not all unicellular have DNA.It is believed that first living cells were bacteria, although other unicellular organisms lived for millions of years before them.


Why cell can be an organism?

Just Because it's so small does not mean it isn't an organism. == Answer== Some organisms are unicellular, meaning that are composed of only one cell. Life started as unicellular organisms which turned more complex later.

They are unicellular organisms. Bacteria, protozoans and certain fungi are unicellular.


Do organs have tissue?

No. Tissues are composed of a variety of cells. A single-celled organism is composed of only one cell. Some unicellular organisms may be colonial, but they do not form true tissues.
