Any organism that lacks a defined true nucleus and membrane-bound organelles is referred to as a prokaryote.
The genetic material is present in the nucleoid in the cytoplasm of the cell.
Bacteria are one of the most well-known types of prokaryotes.
Prokaryotes differ from eukaryotes because of the absence of nuclei and organelles.
Prokaryotes have 70 S ribosomes.
Examples of prokaryotes include cyanobacteria, E. coli, Mycoplasma, etc.
Eukaryotic cell:
Any organism with a clearly defined nucleus is known as a eukaryote.
The nucleus of a eukaryotic cell is surrounded by a nuclear membrane, which contains well-defined chromosomes (bodies containing the genetic material).
They have membrane-bound organelles such as mitochondria, endoplasmic reticulum, Golgi bodies, etc.
Examples of eukaryotes are plants, animals, protists, and fungi.
