Kingdom Monera
Unicellular prokaryotes found nearly everywhere.
Tiny but everywhere
Bacteria are found in soil, water, air and hot springs, and even inside human bodies.
Do you think all bacteria cause disease?
What this lesson covers
The idea
Kingdom Monera comprises unicellular prokaryotes, bacteria and cyanobacteria; bacteria live everywhere, even in extreme environments and inside human bodies, some causing disease and many being useful, while cyanobacteria are autotrophs.
Tiny but everywhere
Bacteria are found in soil, water, air and hot springs, and even inside human bodies.
Do you think all bacteria cause disease?
- No, many are useful
- Yes, all are harmful
- Yes, but only in hot springs
Inside Monera

Monera in short
Monera is made of tiny single cells with no true nucleus. Bacteria live in many places, even extreme ones, and some cause disease while many are useful. Cyanobacteria make their own food.

Notes
Monera are unicellular prokaryotes: bacteria (some harmful, many useful) and cyanobacteria, which are autotrophs.

Which statement about bacteria is correct?
How do cyanobacteria get their food?
- Bacteria and cyanobacteria — correct. Yes!
- Mushrooms and yeast. These are placed under Fungi.
- Amoeba and Paramecium. These are single-celled eukaryotes, which are grouped under Protista.
- Many-celled eukaryotic cells. Monera are unicellular prokaryotes.
- Single-celled prokaryotic cells — correct. Yes!
- Single-celled eukaryotic cells. Single-celled eukaryotes are grouped under Protista.
- All bacteria cause disease. Many bacteria are useful, for example Lactobacillus and Rhizobium.
- Bacteria cannot live in extreme environments. Bacteria live in hot springs and other extreme environments where most organisms cannot survive.
- Some are harmful and many are useful, like Lactobacillus and Rhizobium — correct. Yes!
- They are autotrophs and make their own — correct. Yes!
- They are heterotrophs and depend on other organisms. The book says cyanobacteria are autotrophs.
- They absorb it through fine filaments. Absorbing nutrients through fine filaments describes fungi.
