Eubacteria and Archaebacteria Overview

Eubacteria

True bacteria with peptidoglycan cell walls.

Archaebacteria

Prokaryotes often found in extreme environments.

Prokaryotes

Single-celled organisms without membrane-bound organelles.

Binary fission

Asexual reproduction.

Extremophiles

Organisms that live in extreme enviroments

Thermophiles

Heat lovers

Acidophiles

Acid lovers

Halophiles

Salt lovers

Peptidoglycan

Structural component of Eubacteria cell walls.

Mesophiles

Moderate lovers

Cocci

Spherical-shaped bacteria.

Bacilli

Rod-shaped bacteria.

Spirilla

Spiral-shaped bacteria.

Colonies

Groups of bacteria working together, not multicellular

Cell wall

Maintains shape and protects bacterial cells.

Obligate aerobes

Bacteria that require oxygen for respiration.

Obligate anaerobes

Bacteria that cannot survive in oxygen.

Facultative anaerobes

Bacteria that prefer oxygen but can survive without it.

Heterotrophs

Organisms obtaining nutrients from other organisms.

Methanogens

Archaea producing methane as a waste product.

Endospores

Bacteria surviving unfavorable conditions.

Antibiotic resistance

Bacteria's ability to resist antibiotic treatment.

Parasites

Feed on living things and cause disease

Saprobes

Feed on dead matter

Autotrophic

Make food by photosynthesis
