Make their own energy

Using Solar energy

Eg. Cyanobacteria

Slide 27

Chemotrophs

Make own Energy

Using Chemical energy

Eg. Archaebacteria

Slide 28

Heterotrophs

Obtain food

By eating

Eg. E-coli

Slide 29

Bacteria Respiration

Obligate Anaerobes

Facultative Anaerobes

Obligate Aerobes

Live without Oxygen

Can live with or without oxygen

Cannot live without oxygen.

Slide 30

Bacteria Reproduction

Binary Fission

Conjugation

Spore Formation

Slide 31

Cellular organism copies it’s genetic information then splits into two identical daughter cells

Slide 32

Conjugation

A type of Bacteria Sex

Two organism swap genetic information, that contains the information such as a resistance to penicillin

Slide 33

Spore Formation: Endospore

A type of dormant cell

Exhibit no signs of life

Highly resistant to environmental stresses such as:

-High temperatures

-Irradiation

-Strong acids

-Disinfectants

Endospores are formed by vegetative cells in response to environmental signals that indicate a limiting factor for vegetative growth, such as exhaustion of an essential nutrient.

Slide 34

Symbiosis

Close relationship between to species in which at least one species benefits from the other

Live together for LIFE

Slide 35

Parasitism

Bacteria exploit the host cell, injuring them

Eg. Mychobacterium tuberculosis

Slide 36

Mutualism

Symbiosis in which two of the species live together in such a way that both benefit from the relationship

Eg. E-coli

Slide 37

Nitrogen Fixations

Process by which nitrogen in the atmosphere is converted into a form that can be used by living things
