ADVERTISEMENTS:
The upcoming discussion will update you about the difference between prokaryotic and eukaryotic cells.
Difference # Prokaryotic Cell:
1. Nuclear membrane is absent in prokaryotic cell.
2. Chromosomes are single in prokaryotic cell.
ADVERTISEMENTS:
3. DNA is naked.
4. Nucleolus is absent in prokaryotic cell.
5. Mitochondria is absent. Respiratory and photosynthetic enzymes present in plasma-membrane.
6. Endoplasmic reticulum is absent in prokaryotic cell.
ADVERTISEMENTS:
7. Ribosomes – 70S type/size, made up of 5OS and 30S sub-units. All ribosomes are free in cytoplasm.
8. In prokaryotic cell, chloroplast is absent. However, present in blue-green algae is associated with lamellae. These lamellae are not enclosed by membrane.
9. Golgi bodies are absent in prokaryotic cell.
10. Lysosome is absent in prokaryotic cell.
11. Cell-Wall is thin. Non cellulosic, contains amino sugars and muramic acid.
ADVERTISEMENTS:
12. Cytoplasmic streaming or Amoeboid movement does not occur in prokaryotic cell.
13. Division of cell is amitosis or direct.
Difference # Eukaryotic Cell:
1. Nuclear membrane is present in eukaryotic cell.
ADVERTISEMENTS:
2. In eukaryotic cell, chromosomes are many in number.
3. DNA is combined with proteins.
4. Nucleolus is present in eukaryotic cell.
5. Mitochondria is present in cytoplasm of eukaryotic cell.
ADVERTISEMENTS:
6. Endoplasmic reticulum is present in eukaryotic cell.
7. Ribosomes – 80S type/size. In plants these dissociate into 60S and 40S sub-units. Most of the ribosomes attached to endoplasmic reticulum. Some ribosomes are free in the cytoplasm.
8. All green plants have typical chloroplasts which have grana.
9. Golgi bodies are present in eukaryotic cell.
ADVERTISEMENTS:
10. Lysosome are present in eukaryotic cell.
11. Cell-Wall is thick, cellulosic, does not contain amino and muramic acid.
12. Cytoplasmic streaming or Amoeboid movement may occur in eukaryotic cell.
13. Division of cell is indirect. Mitosis and Meiosis.
