Eukaryotic cells have a nucleus, prokaryotic cells do not.
Eukaryotic examples are animal and plant cells
Prokaryotic example would be bacterial cell

Prokaryotic cells do not have a nucleus whilst eukaryotic cells do! An easy way to remember this is by telling yourself 'eu' is 'yes' due to the similarly in wording so in essence- eukaryotic yes nucleus!

Hi Elizebeth,
Thanks for your question.
So cells come in two main types:
prokaryotic
eukaryotic.
Prokaryotic cells are simpler and smaller. They do not have a nucleus or other specialised structures called organelles that are enclosed by membranes. This means their genetic material, DNA, is not stored in a nucleus but is instead found in a region of the cell called the nucleoid. Bacteria are a common example of organisms with prokaryotic cells.
Eukaryotic cells, on the other hand, are more complex and larger. They have a defined nucleus, where the DNA is kept separate from the rest of the cell. Eukaryotic cells also contain various membrane-bound organelles, such as mitochondria (power generators of the cell), endoplasmic reticulum (where proteins and lipids are made), and Golgi apparatus (sorts and packages proteins). Plants, animals, fungi, and protists are all made up of eukaryotic cells.
In summary, the key difference between prokaryotic and eukaryotic cells is in their complexity: prokaryotic cells are basic with no nucleus or membrane-bound organelles, while eukaryotic cells have a nucleus and organelles, making them more complex and capable of performing a wider range of functions.

Prokaryotes are unicellular (single celled) organisms, such as bacteria. Prokaryotic cells lack complex features such as organelles and also lack nuclei, which are central features of eukaryotic cells; instead, their DNA is free in the cytoplasm. Additional plasmids (small loops of DNA) can also be found in prokaryotes. Prokaryotes typically have a cell wall in addition to a cell membrane.
Eukaryotic cells are found in multicellular organisms such as plants and animals. These may contain many organelles, such as chloroplasts and mitochondria. A key feature is the presence of a membrane-bound nucleus, in which their DNA can be found.
Prokaryotic cells are also much smaller than eukaryotic cells, ranging from 0.2 micrometers to 2.0 micrometers, in contrast to eukaryotic cells which can range from 5 micrometers to 100 micrometers.

Click here to view my profile and arrange a free introduction.Prokaryotic cells have no true nucleus, they contain free genetic material and plasmids (rings of DNA). Eukaryotic cells do contain a whole true nucleus which contains all genetic material inside. Prokaryotic cells do not contain any mitochondria where as Eukaryotic cells do contain mitochondria. An example of a Prokaryote would be a bacteria cell, and an example of a Eukaryote would be a plant cell.
Prokaryotic cells, found in bacteria and archaea, are more simple. These cells lack a true nucleus and membrane-bound organelles, and their genetic material is in the form of circular DNA. However, in eukaryotic cells, prevalent in plants, animals, fungi, and protists, possess a distinct nucleus, surrounded by a membrane, and house various membrane-bound organelles that compartmentalize cellular functions.
Prokaryotes are unicellular in comparison to eukaryotes that are most multicellular, though some are unicellular. In prokaryotes the nucleus and membrane-bound organelles are absent, but in eukaryotes they are present. The complexity of a prokaryotes is much simpler and they are much smaller (0.1-5 micrometres), but eukaryotes are more complex and large (10-100 micrometres). The DNA form of a prokaryote is circular, whilst for eukaryotes it’s linear.

Hi Elizabeth,
The main differences between eukaryotic and prokaryotic cells are:
- eukaryotic cells are usually 10 time bigger.
- eukaryotic cells are more complex.
- eukaryotic cells have a nucleus whereas prokaryotic cells don't.
- prokaryotic cells have a single strand of DNA floating in the cytoplasm whereas eukaryotic cells have their DNA in their nucleus.
- prokaryotic cells have plasmids (small rings of extra DNA that float in the cytoplasm).
I hope this helps.
