Prokaryotic cells do not have a definite nucleus whereas eukaryotes have a nucleus. Prokaryotic cells the genetic material float freely and is not enclosed within a nuclear membrane whereas in eukaryotic cells the genetic material is enclosed within a nuclear membrane. Prokaryotic cells do not have membrane bound organelles whereas eukaryotes have membrane bound organelles. Prokaryotic cells are ten times smaller than the eukaryotic cells.
Prokaryotes don't have a well defined nucleus like eukaryotes. They keep their circular chromosome in the cytplasm. It's generally anchored to the inner membrane of the cell. The area where the chromosome is in the prokaryotic cell is often referred to as the nucleoid, since it resembles the eukaryotic nucleus in that the DNA is there (but it's not membrane bound like in eukaryotes). Pretty much in the cytoplasm. ;)
What evidence is there to support the theory that mitochondria and chloroplasts originated as prokaryotic cells?
Prokaryotic and eukaryotic cells have in common the genetic material, that is, presence of DNA Along with DNA, prokaryotic and eukaryotic cells have in common the presence of RNA Prokaryotic and eukaryotic cells, both have a cell membrane covering them The prokaryotic and eukaryotic cells similarities are seen in their basic chemical structures. Both are made up of carbohydrates, proteins, nucleic acid, minerals, fats and vitamins Prokaryotic and eukaryotic cells have in common ribosomes, that…
