Transcript What kind of impact do bacteria and viruses have on the world

What do you
remember about
bacteria?
Remember!

Monera is classified as a Kingdom.
There are two Moneran Kingdoms:
Archaebacteria
Eubacteria
pneumonia
Archaebacteria
Kingdom
• Live in harsh conditions like hot springs.
Ex. The yellow and orange rings around hot
springs.
Eubacteria
Kingdom

•
Germs in you.
Live in soil, water and human body.
Causes milk to become yogurt.
Causes ear, sinus infections, and pneumonia
Bacteria
• Have no nucleus b/c they are prokaryotes.
• Smallest organisms but the most abundant.
Ex. 2.5 billion in one pencil eraser size of soil.
• 1st bacteria found in surgeonfish.
So, if bacteria are so
numerous, how do
bacteria reproduce?
Binary Fission
•
Bacteria pulling apart into 2 cells.
In which stage of binary
fission is the picture
above?
STRUCTURE OF BACTERIA
But, where do bacteria
reproduce?
Warm, moist environments!
What if it is a cold environment?
Endospores
• Are bacteria that grow a thick protective
membrane to live harsh environments.
(Sorta like a coat!)
Ex. Insects in amber with endospores in their digestive
tracts.
Shapes of Bacteria
Bacilli
(buh SIL ie)
• Rod shaped
Cocci
(KAHK sie)
• Circular
Spirilla
(spie RI luh)
•
Spiral
Bacteria of the Day!
Cyanobacteria
•
•
•
•
Live in water.
Live in cells with nuclei.
Make food from the sun.
Protected by host.
Ticket out the door:
1. Draw and explain binary
fission
2. Why this is beneficial or
harmful for humans and
bacteria?
