Differences Between Prokaryotic and Eukaryotic Cell
Now let us study the difference between Prokaryotic and Eukaryotic Cells
Prokaryotic Cell | Eukaryotic cell |
Size is 0.1- 5.0 um | Size is 5-100 um |
Nucleus is absent | Nucleus is present |
Membrane-bound nucleus absent. | Membrane-bound Nucleus is present. |
One chromosome is present, but not true chromosome plastids | More than one number of chromosomes is present. |
Unicellular | Multicellular |
Lysosomes and Peroxisomes absent | Lysosomes and Peroxisomes present |
Microtubules absent | Microtubules present |
Endoplasmic reticulum absent | Endoplasmic reticulum present |
Mitochondria absent | Mitochondria present |
Cytoskeleton absent | Cytoskeleton present |
Ribosomes smaller | Ribosomes larger |
Vesicles present | Vesicles present |
Golgi apparatus absent | Golgi apparatus present |
Chloroplasts absent; chlorophyll scattered in the cytoplasm | Chloroplasts present in plants |
Submicroscopic in size Flagella is present and made up of only one fibre | Microscopic in size, membrane-bound |
Cell wall chemically complexed | The cell wall is present in plants and fungi and chemically simpler |
Vacuoles absent | Vacuoles present |
The permeability of the nuclear membrane is not present | The permeability of Nuclear membrane is selective |
Sexual reproduction is absent | Sexual reproduction is present |
Endocytosis and exocytosis are absent. | Endocytosis and exocytosis occurred |
It may have pili and fimbriae. | Pili and fimbriae are absent |
Transcription occurs in the cytoplasm | Transcription occurs inside the nucleus. |
Examples: Bacteria and Archaea | Examples: Protists, Fungi, Plants, and Animals |
Therefore, we can say that on the basis of genetic materials enclosed by a nuclear envelope, cells are divided into prokaryotes and eukaryotes. Prokaryotes don’t have membrane-bound organelles whereas eukaryotes have.
