Question

Describe the general characteristics of kingdom Monera.

Answer 1

Hint: Monera are species of unicellular, prokaryotic organisms that are found in a moist environment and it is also the organism that lacks a true nucleus. They can be present or can be found in hot springs, deep oceans, snow and as parasites in organisms. Kingdom Monera consist of all prokaryotes that contain no nucleus.

Complete answer:
The different general characteristics of Kingdom Monera include:
- The Monerans are unicellular organisms that lack a nucleus.
- They contain the 70S ribosomes
- It lacks the main organelles mostly like Golgi bodies, Endoplasmic reticulum, Centrosome, Mitochondria etc.
- They mainly reproduce asexually mainly binary fission or budding.
- The cell wall is made of peptidoglycan and it is very rigid.
 - Flagellum is serving as their locomotory organ.
- They famously known as the environmental decomposers
- They exhibit different modes of nutrition like autotrophic, parasitic, heterotrophic or saprophytic.

Note: Monerans are very useful organisms in nature. They help in enriching the soil and serve as an important part of the nitrogen cycle.They are of great help in the production of some food items and antibiotics. Methanogens are very vital where the treatment of sewage is concerned. Many organisms rely on archaebacterial as the source of food.Monera breakdown the dead matter and food in our digestive systems. They also prepare their own food but bacteria feed mainly on dead matter.
Monerans are further divided into three phyla: Archaebacteria, Eubacteria, Cyanobacteria.
They reproduce sexually by a process called conjugation.They are also found in different shapes mainly Spirillum, filament, stalked, budded etc.
