The nucleus's main function is to hold the DNA. Prokaryotic cells do have the DNA but it is not surrounded by a membrane that separates it from the rest of the cell so the DNA just floats around in the region called nucleiod instead of being confined inside a nucleus.
Prokaryotes are the simplest organisms. They are single celled without organelles like a nucleus or mitochondria.
Prokaryotes are simple cell structures without a nucleus
A simple organism without nucleus: an organism whose DNA is not contained within a nucleus
Cells with a nucleus are called eukaryotic cells, while cells without a nucleus are called prokaryotic cells. Eukaryotic cells have their genetic material enclosed within a membrane-bound nucleus, whereas prokaryotic cells have their genetic material free-floating in the cytoplasm.
There are three main differences between prokaryotes and eukaryotes. Prokaryotes lack a cell nucleus while eukaryotes are made up of cells that all contain a membrane bound nucleus. While prokaryotes have a single cell make-up, eukaryotes have multiple cells. Prokaryotes has DNA without any real structure, while eukaryotes has a well structured DNA system that is organized into chromosomes.
Monerans are prokaryotes.
Prokaryotes
An organism without a nucleus is called prokaryote. Prokaryotes include bacteria and archaea. They have their genetic material (DNA) located in the cytoplasm without a membrane-bound nucleus.
Cells with a nucleus are known as eukaryotes. Cells without nulcei are called prokaryotes.
Prokaryotes are single-celled organisms without a distinct cell nucleus or membrane-bound organelles. They belong to the domains Bacteria and Archaea, which are separate from the domain Eukaryota that includes eukaryotes.
Bacteria are most commonly prokaryotes and have no membrane-bound organelles which includes the nucleus.
Prakariyotes are without nucleus and membrane bound organells.Eukariyotes have nucleus and membrane bound organells.
