Answer:
Which statement about bacteria is TRUE?a. All bacteria are multicellular organisms. b. Bacteria do not use the same genetic code as organisms in other domains. c. Bacteria are in a domain of their own. d. Archaea belong to the same domain
The answer to the question is Option C (Bacteria are in a domain of their own)
Explanation:
There are eight distinct taxonomic categories:
- Domain
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species
A domain, is a taxon in the highest rank of organisms, higher than a kingdom in the classification of life.
The three domains are the Archaea, the Bacteria, and the Eukarya.
Organisms are placed into domains and kingdoms based upon their:
- Cell type
- Their ability to make food
- The number of cells in their bodies
Members of the domain bacteria are called Prokaryotes.
Bacteria are not multicellular organisms. They are large group of unicellular microorganisms.
Bacteria are single-celled microorganisms that does not have a nucleus or any other membrane and they can exist either as free-living organisms or as parasites.
The most common four Bacteria are: Micrococcus, Staphylococcus, Bacillus, and Pseudomonas. Bacteria and eukaryotes have membranes composed mainly of glycerol-ester lipids.
Archaea have membranes composed of glycerol-ether lipids. Archaea are any group of single-celled microorganisms with no cell nucleus or any other organelles inside their cells. They have distinct molecular characteristics separating them from bacteria.
Archaea are prokaryotes that share certain characteristics with bacteria.
Bacteria aren’t placed in a kingdom by themselves, they have their own domain.
Bacteria are placed in their own domain, because of morphology and especially ancestry, like any other organism.
Bacteria are in a domain of their own is the statement that is true about bacteria.
Bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.
- Although formerly the term "bacteria" grouped all prokaryotic organisms, today the taxonomy divides them into two categories: the Bacteria domain and the Archea domain.
- Both are grouped in the Prokaryota superkingdom, made up of all prokaryotic organisms, which constitute the most primitive and most abundant living beings on planet Earth, adapted to practically all conditions and habitats.
Therefore, we can conclude that the bacteria domain contains exclusively prokaryotic organisms, with a simple and primitive cellular structure, which are considered the most abundant forms of life on the planet.
