Monera
Monera
Single-celled organisms without a nucleus or membrane-bound organelles. They have a rigid cell wall and come in various shapes.
Eubacteria
Eubacteria
True bacteria with strong cell walls that are found in various shapes and forms. They can be either autotrophs or heterotrophs.
Archaebacteria
Archaebacteria
Ancient bacteria with different cell walls than regular bacteria. They make their food via chemosynthesis or photosynthesis and are often found in extreme environments.

Study Notes
Monera Kingdom Overview
- Monera includes Eubacteria and Archaebacteria.
- Eubacteria (true bacteria) have strong cell walls and diverse shapes.
- Archaebacteria (Archaea) have distinct cell walls from bacteria.
- Archaebacteria are chemosynthetic and photosynthetic, creating their own food.
- Archaebacteria inhabit extreme environments like swamps, deep-sea vents, and evaporating ponds (often oxygen-less).
- Eubacteria live in most habitats (excluding most extreme conditions).
- Some eubacteria are heterotrophs (consuming others for nutrients) while others are autotrophs (produce their own food).
- Photosynthetic eubacteria produce food like plants.
- Chemosynthetic eubacteria create energy through chemical reactions.
- Some eubacteria cause diseases such as strep throat and pneumonia.
- Most eubacteria are harmless and beneficial.
Key Characteristics of Monera
- Simple prokaryotic unicellular organisms.
- Lacks a well-defined nucleus and membrane-bound organelles.
- Primarily have rigid cell walls.
- Exhibits diverse nutritional modes (autotrophs or heterotrophs).
- Crucial as decomposers and mineralizers in the biosphere.
