Question

Difference between Prokaryotic and Eukaryotic cell​

Answer 1

$\huge\underline\mathfrak\red{Answer}$

PROKARYOTIC CELLS :-----

THE CELLS OF FALSE NUCLEUS IS CALLED AS PROKARYOTIC CELLS.

The cell without cell defined nucleus is called Prokaryotic cells.

Cell size is generally small.

Only a single Chromosome is present.

Cell division is by budding or fission.

_________________________________

EUKARYOTIC CELLS :----

EUKARYOTIC ARE THE ORGANISMS WHOSE CELL HAVE NUCLEUS ENCLOSED WITHIN A MEMBRANE.

The cell with well defined nucleus is called Eukaryotic cells.

Cell size is generally large.

More then one chromosome is present.

Cell division is by meiotic.

Answer 2

Answer:

Prokaryotic Cell :

1. The cell size is usually small.
2. Nuclear region is poorly defined due to absence of nuclear envelope. Nucleoide is not surrounded by a nuclear membrane and is in direct contact with the cytoplasm.
3. Nucleoid is equivalent to a single chromosome or prochromosome. Hence the amount of DNA is comparatively low.
4. Nucleolus is absent.
5. Protein synthesis occurs only in cytoplasm.
6. Membrane bound organelles are absent.
7. Ribosomes are of 70S type.
8. Centrioles are absent.
9. True sap vacuoles are usually absent. Instead gas vacuoles may be found.
10. Thylakoids, if present, lie freely in cytoplasm.
11. Additional small circular DNA segment or plasmids may occur.
12. Having single envelope system.

Eukaryotic Cell :

1. The cell is comparatively large.
2. Distinct nucleus is present
3. . Nucleus contains more than one chromosome. Hence, the amount of DNA is
4. Nucleolus is present.
5. Protein synthesis takes place in cytoplasm, mitochondria and plastids.
6. Membrane bound organelles are present.
7. Ribosomes are of 80S type: 70S type ribosome occurs in mitochondria and plastids.
8. Centrioles are usually present.
9. True sap vacuoles are commonly found, e. g., plant cells.
10. Thylakoids, if present are grouped inside chloroplast as granum.
11. Plasmids are absent.
12. Having double/two envelope system.
