differences between prokaryotic and eukaryotic cells

The biggest different is that Profaryotics cell don't have cell organ and eukaryotic cell. The prokaryotic cells are one cellulor organism (for example bacteria) and eukaryotic cells are multicellular (which means all cells work together for one function, for example human cells and plant cells).

prokaryotic cells do NOT have a nucleus or any membrane bound organelles, whereas eukaryotic cells do.

THE MAJOR DIFFERENCE BETWEEN THE PROKARYOTIC AND EUKARYOTIC CELL IS THAT PROKARYOTIC CELL HAVE PRIMITTIVE TYPE OF NUCLEUS IN WHICH THEIR GENETIC MATERIAL IS NOT ENCLOSED BY A NUCLEAR MEMBRANE. BUT IN EUKARYOTIC CELL AS THE NAME SUGGESTS EU MEANS TRUE AND KARYON MEANS NUCLEUS. SO THOSE ORGANISMS WHO HAVE TRUE NUCLEUS IN WHICH THE GENETIC MATERIAL IS ENCLOSED BY NUCLEAR MEMBRANE IS CALLED EUKARYOTIC. IN PROKARYOTIC CELL MEMBRANE BOUND ORGENELLES ARE ABSENT LIKE MITOCHONDRIA, CHLOROPLAST, ER, GOLGI BODY ETC. EXCEPT RIBOSOME OF 70 S TYPE. BUT IN EUKARTIC CELL ALL THE MEMBRANE BOUND ORGENELLES ARE PRESENT INCLUDING RIBOSOMES OF 80S TYPE. DNA IS CIRCULAR AND NAKED IN PROKARYOTES AND IT IS LINEAR AND COVERED BY HISTONIC PROTEIN IN EUKARYOTES. EXAMPLES OF PROKARYOTES ARE BACTERIA, PPLO, BGA {CYANOBACTERIA} ETC. AND EXAMPLE OS EUKARYOTES ARE ALGAE, PROTISTA, PLANTS ETC.

THERE ARE MANY MORE DIFFERENCES EXCEPT THESE IF YOU WANNA KNOW IN DETAIL LET ME KNOW.

prokaryotic means have primitive type of nucleus ie Nucleus is not bounded by membrane while eukaryotic cell have membrane bounded nucleus.

Prokaryotic cells do not have internal organelles with membranes, such as mitochondria and nucleus. Prokaryotic cells are very simple cells such as bacteria.

Eukaryotic cells are more complex cells such as plant and animal cells and have membrane bound organelles such as mitochondria and nucleus.

Eukaryotic Cells contain organelles such as mitochondria and nucleus. They are much larger than prokaryotic cells.

Prokayotic cells does not have membrane-bound cells, it's structure may have features that resemble these, however, they are not true membrane-bound cells. Although, they are smaller than Eukaryotic cells they make up most of Earth's biomass.

Firstly, prokaryotic are unicellular and eukaryotic are multicellular. Prokaryotes are bacterial and eukaryotic are protists, fungi, animals and plants. Prokaryotes contain: a nucleoid, ribosomes, cell wall, cell membrane, capsule, pills, flagella and fimbriae. Eukaryotes are membrane bound and contain: nucleus, nucleolus, plasma membrane, ribosomes, mitochondria, endoplasmic reticulum, vesicles and a vacuole. DNA is circular in a prokaryote and in a eukaryote is linear.

Eukaryotic cells have a membrane-bound nucleus and membrane-bound organelles ,whereas prokaryotic cells do not. DNA in prokaryotes is naked,found free in the cytoplasm. Prokaryotes reproduce by binary fission whereas eukaryotes reproduce by mitosis .

There are many differences between prokaryotic and eukaryotic cells.

Usually, prokaryotic cells have only one cell per organism and eukaryotic cells are multicellular, though this is not a rule as a eukaryotic organism like yeast is unicellular.

The textbook answer is that eukaryotic cells have a membrane bound nucleus, whereas prokaryotic cells have a free 'floating nucleus' in the form of circular DNA.

Hi Elizabeth. Great question - this comes up frequently in exam papers!

Prokaryotic cells (for example bacteria) tend to have free genetic material whereas eukaryotic cells (like plant cells and the cells which make up your body) tend to have a membrane around their genetic material. The genetic material (DNA) is also neatly wound around proteins called histones and is more organised.

Eukaryotic cells also have membrane-bound organelles within them to help carry out various roles within the cell such as mitochondria, chloroplasts (in plant cells), Golgi bodies and so on.

Hope this helps! If you would like further explanation, do get in touch.

Prokaryotic cells have no nucleus and are unicellular

Eukaryotic cells have a nucleus and are multicellular

Tip to help you remember:

Pro rhymes with 'no' (as in Prokaryotes = no nucleus)

Eu rhymes with 'nu' (as in Eukaryotes = nucleus)

Hope this helps!

Eukaryotic cells are typically larger and more complicated than prokaryotic cells. Eukaryotic cells have organelles, specialised structures that keep things separate and let them carry out distinct processes separate from the rest of the cell. So eukaryotic cells have organelles like nuclei and mitochondria and chloroplasts, which are enclosed in a membrane, and the environment inside the organelle can be very different than the cytosol outside. In prokaryotic cells, everything is not clearly separated, for example, instead of a nucleus, the DNA is just in the cytoplasm.

That is the general rule, but for something more specific, these are the things that you should expect to find in both prokaryotes and eukaryotes:

Cell membrane, DNA, cytoplasm, ribosomes, may or may not have a cell wall.

These features are only found in prokaryotes:

The DNA is circular and in the cytoplasm, the ribosomes are smaller, the cell wall is made of murein. There may/may not be a flagellum, a capsule (slimy coat), or plasmids.

These are the features only found in eukaryotes:

Membrane-bound organelles (e.g nuclei, mitochondria, chloroplast, endoplasmic reticulum etc), the ribosomes are larger. If it is a plant cell, there will be a cell wall made of cellulose. The DNA (which is inside the nucleus) is organised into chromosomes.

If it helps to remember this, prokaryotic cells are normally too small to fit things like organelles, because they are about the same size as organelles!

Hope that helps

Prokaryotic cells have cell walls, flagellum, plasmids (circular DNA), loose DNA. Where as eukaryotic cells DNA is linear, they have nucleuses, mitochondria. Plant and fungi cells do have cell walls whereas animal cells do not.

Eukaryotic cells are cells that contain organelles that are bounded by membranes. They can include both unicellular and multicellular species. I suppose the most distinct difference between Eukaryotes and prokaryotes are that Eukaryotes have a nucleus and a linear DNA structure.

On the other hand, Prokaryotic cells lack a nucleus and a circular DNA. They are strictly single celled and Membrane-bound organelles are absent.

Eukaryotic cells have a membrane bound nucleus and prokaryotic cells do not.
