Kingdom MoneraBacteria

PA State Standards

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

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.
