Final answer:
Bacteria don't need to sort their chromosomes because they have a simpler cell structure compared to eukaryotic cells. During mitosis in eukaryotes, chromosomes are sorted and separated to ensure each daughter cell receives the correct number of chromosomes.
Step-by-step explanation:
The reason bacteria don't need to sort their chromosomes is because they have a simpler cell structure compared to eukaryotic cells. Bacteria have a single, circular chromosome and no nucleus, while eukaryotic cells have multiple linear chromosomes contained within a nucleus. During mitosis in eukaryotes, the duplicated DNA is sorted and separated to ensure each daughter cell receives the correct number of chromosomes. This is necessary because eukaryotic cells have multiple chromosomes that need to be accurately distributed to maintain the genetic integrity of the organism.
