They lack a nucleus.
They are prokaryotes.
They are unicellular.
They are both prokaryotes
They are both unicellular.(apex)
They have no nucleus and are unicellular but so are some animals from the kingdom
Animalia.
They are both prokaryotes
They are both unicellular.(apex)
They do not have nucleuses, their DNA is floating about freely in the cell.
How are organisims in the bacteria and archaea domains similar
They are unicellular. (another one for APEX)
the are unicellular - apex
they are unicellular - apex
They are prokaryotes
Protists and bacteria are grouped into different domains because the Protists are more complex and contain a membrane backed nucleus which bacteria lacks. Furthermore, Protists eat bacteria and bacteria decomposes Protists. Bacteria is not made of cells and Protists are photosynthetic.
Carl Woese, of the University of Illinois, discovered archaea. He realized that while these creatures - the smallest, simplest organisms on earth - were similar to bacteria, and shared bacteria's key feature (no nucelus), their genes greatly resembled those of more advanced cells. He proposed that these new organisms be classified in their own kingdom, today known as "archaea."
Archaea bacteria has a similar cell organization to regular bacteria. They are simple, single cell organisms. Like other bacteria, they have no cell nucleus. They are around 5 micro meters long.
Both are Prokaryotic, so they don't have a nucleus. They both have circular chromosomes, and their ribosomes are fundamentally similar in structure
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?
they are unicellular
Both have a cell wall
they look similar, they have similar DNA, they are both very ancient organisms, they both perform the same ecological function
They are unicellular
Protists and bacteria are grouped into different domains because the Protists are more complex and contain a membrane backed nucleus which bacteria lacks. Furthermore, Protists eat bacteria and bacteria decomposes Protists. Bacteria is not made of cells and Protists are photosynthetic.
like bacteria members of the domain archaea are unicellular prokaryotes
Archaea
Yes, archaea have similar chemical make up to bacteria.

They look similar.
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.
