Eukraryotic cells have a membrane bound nucleus and organelles whilst prokaryotic cells have free floating DNA with no nucleus
Eukaryotic have nuclues and membrane bound organelles. While prokaryotic do not have any of these.

Prokaryotic cells have no membrane-bound organelles including a nucleus. The DNA of many prokaryotes can be found in a chromosomal loop of DNA or in plasmids.

Prokaryotic cells are single celled organisms such as bacteria and viruses. They do not have a nucleus but they contain DNA. Eukaryotic cells are present in multi-cellular organisms such as plants and animals and do contain a nucleus.

Prokaryotic cells do not have a membrane and are always a part of unicellular organisms , whereas eukaryotic cells are membrane-bound organisms and are mutlicelluar.

Click here to view my profile and arrange a free introduction.The main difference between prokaryotic and eukaryotic cells is that eukaryotic cells have membrane-bound organelles, meaning that their sub cellular components such as the mitochondria, and most importantly the nucleus (where the DNA is kept) are surrounded by an extra layer of protection known as a membrane.
In prokaryotic cells, all sub cellular structures are floating around in the cytoplasm, even the DNA; though the DNA is coiled up and mostly floats in an area of the cell known as the nucleoid.
There are some other major differences, such as prokaryotic are really small in comparison to eukaryotes, their chromosomes are circular and short, where as eukaryotes have linear and longer chromosomes and the type of ribosomes that they have are also different.
Prokaryotic cells are smaller, has cell wall, and contains DNA floating freely in the cytoplasm unlike eukaryotic cells where DNA is being enclosed in a nucleus.
Eukaryotic cells are cells like animal or plant cells.
prokaryotic cells are cells like bacteria.
The key difference between the two is that Eukaryotic cells contain membrane bound organelles whereas prokaryotic cells do not. They also have variable (different) organelles, for example eukaryotic cells have a nucleus whereas prokaryotic cells do not!

Eukaryotic cells have membrane bound organelles whilst prokaryotic cells don't. For example, as the nucleus is a membrane bound organelle, prokaryotic cells don't have nuclei. Instead, they have their genetic material in a single chromosome of circular DNA (without any introns). Eukaryotic cells, on the other hand, have linear, protein-bound DNA containing introns. Prokaryotic cells also tend to be smaller, and contain 70S ribosomes, whilst eukaryotic cells contain 80S ribosomes. Prokaryotic cell walls are typically made up of peptidoglycan (murein), whilst eukaryotic cell walls, if present, are made of cellulose, or chitin in fungi.
You can actually link some of the differences between prokaryotic and eukaryotic cells to the endosymbiotic theory - that some eukaryotic organelles, e.g. mitochondria or chloroplasts, evolved from free-living prokaryotes.

Click here to view my profile and arrange a free introduction.Nucleus:
Prokaryotic: Lacks a true nucleus; genetic material is in the nucleoid region.
Eukaryotic: Contains a well-defined nucleus where genetic material is enclosed in a membrane.
Membrane-Bound Organelles:
Prokaryotic: Lacks membrane-bound organelles.
Eukaryotic: Contains various membrane-bound organelles like the endoplasmic reticulum, Golgi apparatus, mitochondria, and more.
Cell Size:
Prokaryotic: Generally smaller in size (1-5 micrometers).
Eukaryotic: Typically larger and more complex (10-100 micrometers).
Cell Division:
Prokaryotic: Reproduces through binary fission.
Eukaryotic: Undergoes mitosis or meiosis for cell division.
Genetic Material:
Prokaryotic: Usually a single, circular DNA molecule.
Eukaryotic: Multiple linear DNA molecules associated with histone proteins.
Ribosomes:
Prokaryotic: Smaller ribosomes (70S).
Eukaryotic: Larger ribosomes (80S).
Cell Wall:
Prokaryotic: May have a rigid cell wall made of peptidoglycan.
Eukaryotic: Plant cells have a cellulose cell wall; animal cells lack a cell wall.
Flagella:
Prokaryotic: Simpler flagella.
Eukaryotic: More complex flagella composed of microtubules.
Reproduction:
Prokaryotic: Asexual reproduction is common.
Eukaryotic: Reproduction can be both asexual and sexual.

Prokaryotic cells are simpler cells found in organisms like bacteria. They don't have a nucleus or any membrane-bound structures inside. Instead, their genetic material floats freely in the cytoplasm. Eukaryotic cells, found in plants, animals, and other organisms, are more complex. They have a nucleus surrounded by a membrane and various membrane-bound structures called organelles, like mitochondria and the endoplasmic reticulum. Eukaryotic cells are usually larger and more specialised than prokaryotic cells.

Click here to view my profile and arrange a free introduction.Hey Elizabeth, The prokaryotic cells are mainly bacterial cells and the eukaryotic cells are the human cells. Now the main difference between them can is that the prokaryotic cells have a cell wall whereas the eukaryotic cells do not. Another difference can be that the genetic material in the prokaryotic cells is not membrane-bound whereas in the eukaryotic cells they can be membrane-bound( nucleus). The eukaryotes have 80s ribosomes whereas the prokaryotes contain 70s ribosomes. The prokaryotes contain plasmids whereas the eukaryotes do not. There are also other differences but I hope this helps :)
