Taxonomy: the process of classifying things based on characteristics.
Organization from large to smallor wide to narrow.

Movement & Support
Have cell walls to support shape and provide protection
Some have flagellum for movement

Digestion/Obtaining Nutrients
Some are autotrophsPhotosynthetic: make food from sunChemosynthetic: make their food from molecules
Some are heterotrophs that use organic molecules that they engulf & breakdown
Some use aerobic respiration and others use fermentation (anaerobic). These processes produce energy

Nervous/Response
Circular chromosome with DNA
Some produce endospores
Some produce toxins

Circulation
Rely on flow of cytoplasm to move materials through cell

Gas Exchange
Gases are exchanged directly to the environment through diffusion

Excretion
Waste is secreted through the cell membrane by diffusion or exocytosis

Reproduction
Asexual – binary fission
Sexual – conjugation through pilus

What makes bacteria so great?
They reproduce rapidlyTheir DNA mutates frequentlyThey can exist in extreme environmentsThey are able to use substances that
other organisms cannot

Vaccines & Immunity
Vaccines consist of dead/destroyed virus or bacteria
Sensitizes the body to the foreign objects
Creates antibodies that recognize foreign antigen
Allows the body to react more quickly when it encounters the “real deal”
