The answer is -Prokaryotic cells have single strands of DNA, and eukaryotic cells have multiple chromosomes.
The main difference between prokaryotic and eukaryotic cells is that eukaryotic cells have long tangled strands of DNA packed in the nucleus, and prokaryotic do not have nucleus and their DNA is short stranded. Since DNA strand are very long in eukaryotic cells, they are organised in chromosomes. The number of chromosomes is different for each species, and 23 chromosomes are characteristic for humans.
