Question

What are the salient features of monera?​

Answer 1

Answer:

Prokaryotes are very tiny, single-celled organisms. These cells' DNA (deoxyribonucleic acid) is not enclosed in a nucleus, instead sitting in a loose assembly in the cytoplasm called the nuceloid. This DNA is in the form of a single circular chromosome. The cells contain no organelles or specialized membrane-bound structures, such as the endoplasmic reticulum, Golgi bodies and mitochondria found in eukaryotic cells. They do contain ribosomes, structures made out of RNA (ribonucleic acid) and proteins that synthesize new proteins. They reproduce by a process called binary fission, which essentially means splitting in two to make two cells identical to each other as well as the parent. These cells have walls, unlike animal cells.

Kingdom Monera:

It is very surprising to know that bacteria alone occupy a complete kingdom in the hierarchy of living organisms. They are the omnipresent organisms of the living world. We can find bacteria almost everywhere. This property can be owed to the fact that bacteria have a wide range of variety and many of them are adapted to survive in extreme environmental conditions. A large number of bacteria also live on other organisms as parasites.

Bacteria can be classified into four major types based on their shape:

Coccus – Spherical shaped

Bacillus – rod-shaped

Vibrium – comma-shaped

Spirillium – spiral-shaped

As far as the mode of nutrition of bacteria is concerned, some of them are autotrophic while rest of them are heterotrophic.
