Prokaryote Anatomy
The name for a chain of spherical bacteria.
What is streptococcus.
This term describes an organism that dies in the presence of oxygen.
What is an obligate anaerobe?
Common form of bacteria reproduction producing two identical daughter cells.
What is binary fission?
This type of microbe is responsible for causing disease in other organisms.
What is a pathogen?
This protective coating of protein surrounds the genetic information of a virus.
What is the capsid?
Unlike bacteria, the members of Kingdom Archaea do not contain this component in their cell walls.
What is peptidoglycan?
An organism that eats other organisms for nourishment.
The specialized protective structure that bacteria form when environmental conditions are unfavourable.
What is an endospore?
Having an excess amount of antibiotic in an environment can lead to large bacteria populations becoming this.
What is antibiotic resistant?
This is the organism that the tobacco mosaic virus infects.
What is the tobacco plant?
These three structures form the outer envelope of a prokaryotic cell.
What are the capsule, the cell wall, and the cell membrane.
The bacteria that will survive with or without oxygen in their environment.
What are facultative anaerobes?
The nucleoid region of a prokaryote's cytoplasm is the location where this genomic structure is stored.
What is the chromosome?
In a test where you hope to examine the effectiveness of a disinfectant against a specific type of bacteria, these are the types of techniques that you use to avoid cross-contamination.
What are aseptic techniques?
These two types of viruses do not use DNA as their genetic material.
What are retroviruses and coronaviruses?
The lack of these internal cell structures is the main difference between a prokaryotic cell and a eukaryotic cell.
What are membrane-bound organelles?
A bacterium that produces its own food, but dies when it is placed in a dark environment.
What is a photoautotroph?
These small, circular pieces of DNA are commonly found in the cytoplasm of bacteria, and may also carry genes for antibiotic resistance.
What is a plasmid?
If an antibiotic shows no effect against a new infection from the beginning, this is the microbe that may actually be responsible.
What is a virus?
Vaccines, which contain non-virulent versions of viruses, are used to do this.
What is to prevent viral infection?
What is a Gram-negative bacterium?
Rhizobia, which are commonly found in the root nodules of legumes, are classified as these types of energy-obtainers because they fix inorganic nitrogen to produce energy for themselves.
What is a chemoautotroph?
Specialized pili are used to transfer genetic material between mature bacteria during this process.
What is conjugation?
As was seen in the Harvard experiment video, bacteria can develop resistance to increasing concentrations of antibiotic when these occur during replication.
What are random mutations?
The viral reproductive cycle in which the host cells break down and release copies of the virus.
What is the lytic cycle?
