Organelles:
* Nucleus: Prokaryotes lack a true nucleus. Their DNA is located in a region called the nucleoid, which is not membrane-bound.
* Membrane-bound organelles: Prokaryotes lack other membrane-bound organelles like mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and chloroplasts.
Other Features:
* Cytoskeleton: Prokaryotes have a less complex cytoskeleton compared to eukaryotes. They lack the microtubules and intermediate filaments found in eukaryotes.
* Internal membranes: Prokaryotes generally have fewer internal membranes than eukaryotes.
* Chromosomes: Prokaryotic DNA is usually circular and exists as a single chromosome. Eukaryotes have multiple linear chromosomes.
* Linear chromosomes: Prokaryotes have a single circular chromosome. Eukaryotes have multiple linear chromosomes.
* Introns: Prokaryotes do not contain introns in their genes.
* Complex protein synthesis: Prokaryotic ribosomes are smaller than eukaryotic ribosomes.
* Cell division: Prokaryotes divide by binary fission, a simpler process than eukaryotic mitosis and meiosis.
It's important to remember that some prokaryotes might have specific features that are not present in all other prokaryotes. For example, some bacteria have specialized structures like flagella, pili, or capsules.
