A bacterial chromosome provides data that is required by the bacteria to survive and reproduce. A plasmid does not. It gives a bacterium "special" attributes in during extreme conditions, such as the ability to do genetic recombination or the resistance to certain antibiotics.

Can a bacteraial plasmid replicate independently of the bacterial chromosome?
Bacteria carry plasmids which is a double stranded DNA . It is how their extra chromosomal DNA is stored, they also have chromosomal DNA.Plasmids are extra-chromosomal DNA in Bacterial cells that replicate independently in cell. Plasmids are ubiquitous- means significant number of bacteria have plasmid and can have more that one plasmids. But Plasmids do not occur in all bacterial isolates.
What are the closed loops of DNA?
Closed DNA (circular) is a characteristic of prokaryotes. Circular DNA that is not on the bacterial chromosome are called plasmids.
What are cryptic plasmids and their properties?
Cryptic plasmids are plasmids that have no known function. They occur in a number of bacterial species. A plasmid is a circular loop of DNA, found, for the most part in prokaryotic cells (bacteria). It is much smaller than the single chromosome. Most bacterial plasmids fall into two main groups. There are relatively few copies per cell of large plasmids, with about 100,000 base pairs. These have enough genes to encode approximately 100 polypeptide chains. There are rather more copies of smaller plasmids that have around 10,000 or fewer base pairs (enough to code for up to about 10 genes). At least some cryptic plasmids have been found to contain replication genes.
How do boys chromosomes differ from girls?
Boys have one x chromosome and a y chromosome, whereas a girl has two x chromosomes.
How do the cells of people with down syndrom differ from those of others?
People with down syndrome have cells with an extra chromosome 21.
Do plasmids have protein?
Plasmids are sections of DNA that are independent of the main chromosome found in prokaryotes. It does not have any proteins other than the ones associated with replication of the plasmid.

How does the chromosome number in a diploid cell differ from the chromosome number in a haploid cell?
The chromosome number in hapliod cell is 1 while the dipliod chromosome has 2
Where is DNA located in prokaryotic cell?
DNA is found in a, usually single, chromosome and in plasmids within the cytoplasm.
How many chromosomes found in the cytoplasm of prokaryote cell DNA?
One circular main chromosome and, perhaps, a number ( 1 to 3 ) of circular plasmids.

A bacterium has one that holds its genetic material?
yes. it has only one chromosome that holds its genetic material, however they may also have plasmids that contain genetic material
How do the structure and location of a prokaryotic chromosomes differ from that of a eukaryotic chromosome?
because they do
How do boys chromosomes differ from girls?
Boys have one x chromosome and a y chromosome, whereas a girl has two x chromosomes.
How do the cells of people with down syndrom differ from those of others?
People with down syndrome have cells with an extra chromosome 21.
What is the extra ring called in bacteria?
The extra ring found in bacteria is called a plasmid. Plasmids are small, circular pieces of DNA that can replicate independently of the bacterial chromosome. They often contain additional genes that can provide advantages to the bacterial cell, such as antibiotic resistance or the ability to metabolize certain substances.
