What are “Prokaryotes and Eukaryotes”?
As we all know that cell is the basic unit of
organisation in all living organisms of the universe. These organisms on the basis
of their cell characters are broadly classified as:
A.
Prokaryotes
B.
Eukaryotes
A. Prokaryotes:
The term Prokaryotes is the combination
of two words i.e., “pro” means primitive and “karyon”
means nucleus. The group is characterised by the lack of nucleus and any membrane bound organelles. Prokaryotes
include Bacteria, Cyanobacteria and Archaea.
B.
Eukaryotes: In contrast to prokaryotes, eukaryotes
(“eu” means true) exhibit a complex
structural organisation comprising membrane
bound organelles such as nucleus, plastids, mitochondria, golgi body,
endoplasmic reticulum, lysosomes etc. Additionally the cells of eukaryotes are
much larger than prokaryotes. This group mainly includes plants, fungi, protists
and animals.
