Because they are a vehicle for the insertion of foreign genes into bacteria.
bacteria is important because inside their their body tissues, it provides them with nutrients.
Most bacteria have a single chromosome.Its DNA is described as circular, because it is in the form of a loop. There are also small rings of DNA called plasmids, but these are not classed as chromosomes.The cholera bacterium, Vibrio cholerae, has two chromosomes.

Bacteria are unicellular organisms that have a cell wall but do not have a nucleus. They have DNA material that are of two types - plasmids and chromosomal. Chromosomal DNA have genetic information and the plasmids have extra information that gives the bacteria genetic advantage such as antibiotic resistance. Some bacteria have a whip like flagellum that helps the bacteria to move along.
Because they are a vehicle for the insertion of foreign genes into bacteria.
Plasmids are important in the phases of bacterial genetics because plasmids are the small circle of DNA for bacteria and is responsible for storing and studying genes. Plasmid is used as the vehicle to genetically engineer bacteria to produce insulin.
R-plasmids contain genes for antibiotic resistance and they can be transferred among bacteria. It is common for gut bacteria of humans and other animals to spread antibiotic resistance this way. It is a problem for humans because many bacteria have become resistant to multiple antibiotics.
Genetics are important to study because it helps us figure out traits of things to help find genetic disorders.
bacteria is important because inside their their body tissues, it provides them with nutrients.
They are less complex and their genomes are easily manipulated. The plasmids in bacteria provide an oppertunity for simple genetic recombination exercises. Bacteria can be easily made to be lab dependent so that if an accidental release occured there would be no contamination because the bacteria can not live outside the lab environment.
Because they were the early studies of genetics.
Bacteria and Viruses are the main objects of study in the field of genetics for two reasons: bacteria are chosen because of their simplicity. Viruses are an interesting area of study because they survive by placing their own genetics into other organisms. This gives rise to the possibility of transplanting foreign and possibly beneficial DNA and RNA into hosts that previously did not have those helpful genes.
all of the above
Because they inherited or borrowed genes for antibiotic resistance on tiny "microchromosomes" called plasmids. The ancestors of these plasmids had grown for many thousands of bacterial generations in medium level concentrations of antibiotics causing strong selection pressure for effective antibiotic resistance genes to those antibiotics.
