Question

 Distinguish between prokaryotic and enkaryotic cells

Answer 1

Prokaryotic cell	Eukaryotic Cell
1. Size of a cell is generally small (1– 10 mm).	1. Size of a cell is generally large (5 – 100 mm)
2. Nucleus is absent (Nuclear region or nucleoid is not surrounded by a nuclear membrane).	2. Nucleas is present (Nuclear material is surrounded by a nuclear membrane).
3. It contains single chromosome.	3. It contains more than one chromosome.
4. Nucleolus is absent.	4. Nucleolus is present.
5. Membrane bound cell organelles are absent.	5. Membrane bound cell organelles such as mitochondria, plastids, endoplasmic reticulum, Golgi apparatus, lysosomes, peroxisomes, etc., are present.
6. Cell division takes place by fission or budding (no mitosis).	6. Cell division occurs by mitotic or meiotic cell division

Answer 2

• Prokaryotic cell:

1. Its diameter ranges from 1 to 2 micron
2. Absence of membrane-bound organelles
3. Nucleus consisting of no nuclear membrane
4. Absence of nucleoli

• Eukaryotic cell:

1. Its diameter ranges from 10 to 100 micron
2. Presence of membrane-bound organelles
3. True nucleus consisting of the nuclear membrane
4. Presence of nucleoli
