What is a Moneran?
• They are unicellular and prokaryotes (no nucleus)
• Small, but bigger than viruses (300 across a period!)
Bacteria and Cyanobacteria

What are the types of Bacteria?
Large Cocci – Sphere shaped bacteria Bacillus – Rod shaped bacteria
Cocci Bacillus
SpirillumVibrio

What are the types of Monerans?
Cyanobacteria – Blue Green Algae
An algal bloom
BACTERIA – both good and bad

Quick look at Cyanobacteria
• A.K.A – Blue green algae
• Contains Chlorophyll (photosynthesis)
• Reproduces quickly – nuisance to pool owners; pond scum
• Prokaryotic

Where can bacteria live?• They are located on your
hands, eyelashes, and the bottom of your shoe.
• Found on plants, animals, and inside plants and animals
• Can live in freezing cold temperatures or in boiling temperatures in extreme environments

3Shapes of bacteria
Cocci (-us) – round bacteria
Bacillus – rod shaped bacteria
Spirillum – Spiral shaped bacteria
Vibrio – found in marine environments - Oysters

Reproduction
This is from one bacteria after 10 hours.
Bacteria division

Reproduction
• Reproduce quickly through the process of binary fission – splitting into two
• In suitable conditions, can divide every 20 minutes!

Where do they get energy? • Are heterotrophs (food &
respiration) and autotrophs (sun & photosynthesis
![Page 11: Kingdom Monera Bacteria PA State Standards. What is a Moneran? They are unicellular and prokaryotes (no nucleus) Small, but bigger than viruses (300 across](https://reader035.vdocuments.site/reader035/viewer/2022072014/56649e795503460f94b78fb2/html5/thumbnails/11.jpg)
Got Energy?
• Saprophyte – send out digestive enzymes (decomposers)
• Parasite – lives in or on and weakens host
• Autotrophs – can make their own food (producers)
Bacillus thuringiensis (bah-sill-us ther-in-gee-in-sis): a.k.a "Bt", a common soil bacterium. Wanted as a natural pest-killer in gardens and on crops.

How can we treat harmful bacteria?Take two of these and call me in the
morning…• Antibiotics –
Chemical substances used to kill or slow the growth of bacteria.
• Anti = against• Bio = life• Greek for Against Life• Do not kill viruses…
only living organisms.
