Kingdom Monera ( Kingdom of Prokaryotes)


Includes all prokaryotic organisms. They are important decomposers and mineralizers.
E coli
E.coli Bacteria
Examples: Bacteria, actinomycetes Filamentous bacteria), Cyano bacteria (Blue green algae)
Monerans can be classified into three major groups:
  1. Eubacteria (True Bacteria)
  2. Cyanobacteria (Blue green algae)
  3. Archaebacteria (Ancient bacteria)
Characters:
Habit and Habitat:
They are commonly found in water, air, soil, and on living and dead organic matters.
Archae bacteria (ancient bacteria) live under extreme environmental conditions like high temperature(800C) , high salt conditions and in the absence of oxygen etc.
Structure:
They are microscopic without nucleus and other membrane  bound  organelles. Most of them have a rigid cell wall.
Nutrition:
Bacteria show two types of nutrition: Autotrophs and Heterotrophs
They prepare food materials using light energy (photo autotrophs) or energy released from chemical reactions (Chemoautotrophs)
Heterotrophic bacteria  may be parasitic, saprophytic and symbiotic in nature.
Reproduction:
Asexual methods (Binary Fission, Endospore formation).
Sexual Methods (Conjugation, transformation, Tranduction)
