What are the characteristics of prokaryotes?

Explanation:

First of all, we need to know that prokaryotes are cells that don't have true nucleus, nor membranes organelles. Its counterpart is eukaryotic cells.

Characteristics of prokaryotes:

Lack an organised nucleus. as we said before, and membrane organelles.The central part of this type of cell is called Nucleoid, there's found its DNA.Its diameter size is from 0.1 to 0.5 micrometers, just bigger than flu virus, for example.Its sized characteristics allow them to participate in ions and molecules processes. This is a important fact, because this habilitates prokaryotes to move fast through all the cell, taking out undesired elements away.Prokaryotes are singled cells or unicellular this means that are simple cells.Its nucleoid contains a single chromosome.
