Subsequently, one may also ask, what are the parts of a bacterial cell and their functions?
Table 2. Summary of characteristics of typical bacterialcellstructures
|Structure Flagella||Function(s) Swimming movement|
|Ribosomes||Sites of translation (protein synthesis)|
|Inclusions||Often reserves of nutrients; additionalspecializedfunctions|
|Chromosome||Genetic material of cell|
|Plasmid||Extrachromosomal genetic material|
Furthermore, what structures are found in bacterial cells? It is a gel-like matrix composed of water,enzymes,nutrients, wastes, and gases and contains cellstructuressuch as ribosomes, a chromosome, and plasmids. Thecellenvelope encases the cytoplasm and all its components.Unlike theeukaryotic (true) cells, bacteria do nothave amembrane enclosed nucleus.
Keeping this in consideration, what is bacteria and its structure?
Structure. Bacteria(singular:bacterium) are classified as prokaryotes, whicharesingle-celled organisms with a simple internalstructurethat lacks a nucleus, and contains DNA that eitherfloats freely ina twisted, thread-like mass called thenucleoid, or inseparate, circular pieces calledplasmids.
What are the functions of bacteria?
Bacteria in the digestive system breakdownnutrients, such as complex sugars, into forms the body canuse.Non-hazardous bacteria also help prevent diseasesbyoccupying places that the pathogenic, ordisease-causing,bacteria want to attach to. Somebacteria protect usfrom disease by attacking thepathogens.
