Question

What are the three major differences between prokaryotic and eukaryotic cells?

Answer 1

Prokaryotic cell:

1. The cell which lacks a well-defined nucleus is called prokaryotic cells.
2. These cells have a primitive organization of genetic material.

Eukaryotic cell:

1. The cell having a well-defined nucleus is called a eukaryotic cell.
2. It lacks respiratory enzymes.

Difference between prokaryotic cell and eukaryotic cell:

Prokaryotic Cell	Eukaryotic Cell
The nucleus is not well defined and is called the nucleoid.	The nuclear region well-defined nucleus with a nuclear membrane.
A single length of only deoxyribonucleic acid (DNA).	Several lengths of genetic material (chromosomes) containing DNA are wound around certain proteins.
Small ribosomes.	Larger ribosomes.
No other cell organelles.	Several organelles like mitochondria, endoplasmic reticulum, chloroplasts, etc.
Examples: Bacteria, archaea, and cyanobacteria.	Examples: Euglena, Amoeba, and all plants and animals.
