WebMost bacteria have a genome that consists of a single DNA molecule (i.e., one chromosome) that is several million base pairs in size and is "circular" (doesn't have ends like chromosomes of eukaryotic organisms). In addition, bacteria may have one or more smaller circular DNA molecules, called plasmids, that contain (usually) non-essential genes. WebFew bacteria have more than one chromosome, whereas several bacteria have linear plasmids and chromosomes. When compared to the linear chromosomes present in …

For example, if a cell was undergoing meiosis, and had a total of 4 chromosomes in it, then 2 of them would go to one daughter cell, and 2 of them would go to the other daughter cell. That makes 2 haploid cells.
