Difference Between Eukaryotic and Prokaryotic cells

Cell is a basic unit of life as it forms all of the living organisms.

The cells are classified into a primitive (earliest) and advanced ones.

The primitive one is prokaryotic while the advanced one is the eukaryotic cell.

The difference between eukaryotic and prokaryotic cells are based on internal and external characters.

But in general sense these cells are basically different terms of nucleus and its content.

So though we can see many differences in terms of physical, chemical and organelle structures, it is primarily nucleus based.

Hence the names pro=before (early) karyotic (nucleus) and Eu=True (current) karyotic (nucleus).

Interestingly, prokaryotes are present in plants and microorganisms but eukaryotes are present in both plants and animals.

# 1 Difference Between Eukaryotic and Prokaryotic cells

Below are the key differences in prokaryotic and eukaryotic cells.

Age on EarthRecently evolved after billions of years of prokaryotes emergedPrimitive and existed much earlier than eukaryotes
SizeCells are big and large with avg size of 10 to 100 microns in diametesCells are very small than eukaryotics with avg size of 1-10 microns
NucleusIs present and with well defined nuclear membrane and chromosomes.Nucleus is absent but nuclear material like chromosomes are present.
Cell structureIs complex with many organelles and their arrangementIs quite simple with few organelles.
Reproduction timeReproduction is slow and prolongedReproduction is very quick like in few minutes
Cell organelles presentMitochondria, lysosomes, peroxisomes, microtubules, endoplasmic reticulum, golgi apparatus are presentAll these organelles are absent in prokaryotes.
ChloroplastsThese are cell organelles involved in photosynthesis.Chloroplasts are absent but chlorophyll pigment is present.
Cell wallMade of steroids, ligninspectin etc.Made of polysaccharides
Ribosomes80S ribosome with two parts are 60S and 40S are present70S ribosome with two parts as 50S and 30S are present.
DNA structureDouble stranded helical DNASingle stranded DNA.
ExamplesAll animal and plant cellsBacteria and few algae.

Besides the DNA and nuclear elements are different as
