Kingdoms
KINGDOMS

ARCHEABACTERIA –live in extreme environments, ex. Hot springs, acid, intestines, mud, sewage

EUBACTERIA – in your body, useful or harmless to you,


Reproduction
REPRODUCTION

Asexual/binary fission – Reproductive process that involves only one parent and produces offspring that is identical to the parent. MITOSIS?

Sexual/conjugation – one bacterium transfers its genetic material into another bacterium.

Figure 13 page 196 in your book


Survival needs
SURVIVAL NEEDS

FOOD – Autotrophs and heterotrophs

RESPIRATION – process of breaking down food to release energy. Most need oxygen, some do not.

ENDOSPORE FORMATION – when conditions are unfavorable for growth. In order to survive these conditions bacteria need to form endospores, a small, rounded, thick walled, resting cell that form inside a bacterial cell.

Can resist freezing, heating, and drying


Bacteria and the living world
BACTERIA AND THE LIVING WORLD

FUEL – Natural gas, Bacteria produce the methane gas used for fuel

FOOD – Bacteria help make certain foods buy giving the food its flavor and structure.

Example – cheese, yogurt, apple cider, olives, sauerkraut

ENVIRONMENT – Recycling, act as decomposers

Cleanup – breakdown oil and dangerous chemicals


Illness and health
ILLNESS AND HEALTH
