What do you remember about

bacteria?

Remember!

• Monera is classified as a Kingdom. • There are two Moneran Kingdoms:

1) Archaebacteria

2) Eubacteria

pneumonia

Archaebacteria Kingdom

• Live in harsh conditions like hot springs.

Ex. The yellow and orange rings around hot springs.

EubacteriaKingdom

• 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?
