Prokaryotic Cells Although no well-defined nucleus is present in prokaryotes, the DNA of the cell is concentrated in one region called the nuclear region. Prokaryotic chromosomes are found in the nucleoid of prokaryotic cells, and they are circular in shape. However, eukaryotic cells have a membrane-bound nucleus and other membrane-bound organelles allowing for compartmentalization of functions. Plant Cells. Prokaryotes lack mitochondria and chloroplasts. 20. It is present in this compartment in the form of linear chromosomes that together constitute the genome. In prokaryotes like in bacteria, the DNA remains in the nucleoid region and does not remain associated with proteins. The division between prokaryotes and eukaryotes is usually considered the most important distinction or difference among organisms. In fact, in a loose sense, they serve as the “mitochondria” of themselves. Explanation: The main difference between prokaryotic and eukaryotic cell is that prokaryotic cells have no nucleus in their cell while eukaryotic cells have nucleus present in the center of their cell. Likewise, what do prokaryotic cells have that eukaryotic cells do not? It is also important to take note that the words above originate from the word karyon which is the greek word for nucleus.
