DIFFERENCES BETWEEN PROKARYOTES AND EUKARYOTES CELLS.

 

 

 

PROKARYOTIC CELL	EUKARYOTIC CELL
Strictly Unicellular organisms.	Can be uni- or multi- cellular organisms.
Cells lack nucleus.	Cells contain membrane-bound nucleus with envelope.
Size ranges between 0.1-5µm in diameter.	Measures about 100µm.
Contain no cell organelles.	Many organelles will be present.
Mostly has complex cell wall structure.	Cell wall may or may not be present.
Small ribosome present in the cytoplasm.	Usually large ribosomes present in the cytoplasm.
Has circular DNA in the nucleoid region.	Has linear DNA inside the nucleus.
Absence of mitochondria.	Mitochondria present.
Plasma membrane surrounds the cell.	Plasma membrane present and encloses all the cell organelles.
Absence of cytoskeleton.	Presence of cytoskeleton.
They possess flagella stretching out from the basal body in the envelope, aids in movement of the cell.	Presence of one or more flagella, usually larger than the prokaryotes.
Plasmids present.	Plasmids very rarely present.
No endoplasmic reticulum, lysosome and other cell organelles.	Contains endoplasmic reticulum, lysosome, vacuoles and other organelles also.
Undergoes asexual reproduction.	Undergoes both sexual and asexual reproduction.
Pilli and fimbriae may present.	Pilli and fimbriae are absent.
Ex : Bacteria and archaea.	Ex : plants, animals, protozoans and fungi.
