Differentiate between eukaryotic and prokaryotic cells

OpenStudy (aroub):

Prokaryotic cells are structurally simple: they do not include a nucleus ( DNA is suspended in the cytoplasm in a circular loop ) or complex organelles such as mitochondria or chloroplast and they are unicellular. Eukaryotic cells, unlike prokaryotes, they contain a nucleus as well as mitochondria, chloroplast, and other complex organelles. The DNA in eukaryotes are found in the nucleus in the form of strands, or threads and they could be unicellular or multicellular.

prokarotic cell are those cells which have absent a true nucleus...but its have nuclolus....and prokaryotic is a greek word which means pro+before or early ,karyotic+nucleus.. e.g such as bacteria... eukaryotic cell are those cells which have present a true nucleus... eu+true,karyotic+nucleus.... they also contain a variety membrene bound organells like mitochondria, g.appartus, lysosomes,plastids etc e.g such as kingdom,ptotista,fungi,plantia and and animalia

OpenStudy (anonymous):

the prokaryotes are primitive cell which don't have a nucleus ,,,,it's DNA is not complicated with proteins ( meaning it has little amounts of proteins) ...it contain additional circular DNA called plasmids which enter in genetic engineering.....the length of it's DNA if stretched is 1.4mm and to fit in the nucleus cavity it has to be packed about 100 times ny small amounts of histones...mitochondria and chloroplasts and considered to be parasitic prokaryotes The eukaryotes are the evolved cells which have a nucleus which is surrounded by a nuclear membrane...it has 46 chromosomes each containing a single molecule of DNA ....the DNA to fit inside the nucleus cavity has to be packed about 100,000 times by large amounts of histones and nonhistones ( which are proteins)....and the eukaryotes contain organelles like mitchondria
