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 is a characteristic of all Bacteria quizlet?
Contain cytoplasm surrounded by a cell membrane & a cell wall . Classified as prokaryotic. 1 circular chromosome found in the cytoplasm. Protects from other cells that try to destroy it.
What is an advantage of using Bacteria instead of chemicals quizlet?
What is an advantage of using bacteria instead of chemicals? Bacteria likely cause less disruption to the natural environment .
Do Bacteria have a nucleus?
Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.
What are the 3 main types of bacteria?
There are three basic bacterial shapes: Round bacteria called cocci (singular: coccus) , cylindrical, capsule-shaped ones known as bacilli (singular: bacillus); and spiral bacteria, aptly called spirilla (singular: spirillum). The shapes and configurations of bacteria are often reflected in their names.
What are 3 characteristics of Archaea?
The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat; (3) the occurrence of ether linked lipids built from phytanyl chains and (4) in ...
What are 3 characteristics of eubacteria?
What characteristics do eubacteria have? Eubacteria or “true” bacteria are unicellular, prokaryotic organisms. It has a lipid-containing cell membrane made from glycerol ester lipids. They are characterized by a lack of a nuclear membrane , a single circular chromosome, and cell walls made of peptidoglycan.
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.
Which characteristics best describe bacteria?
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.
What is the advantage of using bacteria instead of chemicals?
What is an advantage of using bacteria instead of chemicals? – Removal of the oil by bacteria is a slow process . – Bacteria likely cause less disruption to the natural environment. – Bacteria do not produce oxygen that could harm the oceans.
Which best describes cost effectiveness?
Answer Expert Verified
Cost-effectiveness can be best described as a way of analyzing a number of different ways in which cost is calculated and incurred and then comparing it with the outcome which can make clear which one of them is most effective and provides the best outcome.
How bacteria are both helpful and harmful to our bodies?
Bacteria help protect the cells in your intestines from invading pathogens and also promote repair of damaged tissue . Most importantly, by having good bacteria in your body, bad bacteria don’t get a chance to grow and cause disease.
What are 4 types of bacteria?
- Coccus form:- These are spherical bacteria. ...
- Bacillus form:- These are rod-shaped bacteria. ...
- Spirilla form:- These are spiral-shaped bacteria that occur singly.
- Vibrio form:- These are comma-shaped bacteria.
Where is the nucleus located in bacteria?
Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus. The chromosome, a single, continuous strand of DNA, is localized, but not contained, in a region of the cell called the nucleoid . All the other cellular components are scattered throughout the cytoplasm.
What type of nucleus does bacteria have?
Bacteria are considered to be prokaryotes, which means they do not have a nucleus and other membrane-bound organelles. Instead, the DNA is found in the nuceloid, a region with no membrane, or as a plasmid, a small circle of extra genetic information, floating right in the cytoplasm, the fluid that fills the cell.
