Lange discovers a colony of bacteria living in an extremely acidic environment. While observing the colony, she finds that the bacteria are autotrophs. Which best describes the bacteria discovered by the scientist? They are probably archaebacteria
Which characteristic describes all bacteria quizlet?
– They are prokaryotic with no nucleus . – They are single-celled organisms. – They can live in extreme environments.
What characteristics describe bacteria?
There are three notable common traits of bacteria, 1) lack of membrane-bound organelles , 2) unicellular and 3) small (usually microscopic) size. Not all prokaryotes are bacteria, some are archaea, which although they share common physicals features to bacteria, are ancestrally different from bacteria.
Which of the following are characteristics of bacteria check all that apply?
Answer: Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella .
Which reason best explains why bacteria can reproduce quickly outer capsule?
Bacteria have a rigid, protective layer that is called a pili. Bacteria are transmitted easily and reproduce quickly .

Which of the following are two characteristics of bacteria quizlet?
A nonliving, non-cellular infectious agent that has two characteristics: (1) It has genetic material (RNA or DNA) inside a protective protein coat. (2) It cannot reproduce on its own.
What are 2 examples of bacteria?
Examples include Listeria monocytogenes, Pesudomonas maltophilia, Thiobacillus novellus, Staphylococcus aureus , Streptococcus pyrogenes, Streptococcus pneumoniae, Escherichia coli, and Clostridium kluyveri.
What is unique about bacteria?
Unique Features
Bacteria lack many of the structures that eukaryotic cells contain. For example, they don’t have a nucleus. They also lack membrane-bound organelles, such as mitochondria or chloroplasts. ... Bacteria also have two additional unique features: a cell wall and flagella .
What is bacteria definition Characteristics & Examples?
Bacteria are single-celled microorganisms with prokaryotic cells, which are single cells that do not have organelles or a true nucleus and are less complex than eukaryotic cells. Bacteria are extremely numerous , and the total biomass of bacteria on Earth is more than all plants and animals combined. ...
What are the names of the 3 domains?
There are three domains of life, the Archaea, the Bacteria, and the Eucarya . Organisms from Archaea and Bacteria have a prokaryotic cell structure, whereas organisms from the domain Eucarya (eukaryotes) encompass cells with a nucleus confining the genetic material from the cytoplasm.
Are bacteria multicellular?
Highlights. Many bacteria have a multicellular phase of their lifecycle , which fall into three broad categories based on shape and mechanism of formation. A number of pressures may have selected for multicellularity, including physicochemical stress, nutrient scarcity, predation, and environmental variability.
What disease does bacteria cause?
Other serious bacterial diseases include cholera, diphtheria, bacterial meningitis, tetanus, Lyme disease, gonorrhea, and syphilis .
What would happen to a bacterial cell?
Based on its shape, what is most likely the form of this bacteria? What would happen to a bacterial cell if its protective covering was destroyed? It would be harmed by chemicals in the environment .
Which type of bacteria can be found in pairs?
Pairs of cocci are called diplococci; rows or chains of such cells are called streptococci; grapelike clusters of cells, staphylococci; packets of eight or more cells, sarcinae; and groups of four cells in a square arrangement, tetrads.
Which best explains why bacteria are good at causing infections in other organisms?
Which reason best explains why bacteria is good at causing infections in other organisms? Bacteria are transmitted easily and reproduce quickly. Consider the classification levels of a human.
