Bacteria Our invisible friends
Bacteria are prokaryotesPro – before Karyon – nucleus The simplest forms of life are prokaryotes. Earth’s first cells were prokaryotes.
Lots of Them! Prokaryotes are Earth’s most abundant life forms.They can survive in many environments. They can get energy from many different sources.
Prokaryote Review Mostly single-celled No nucleus or organellesCircular chromosomes Cell walls Reproduce mostly asexually Anaerobic or aerobic Heterotrophic or autotrophic
Archaebacteria Methane producers – anaerobic Halophiles ThermophilesHalo = salt Philia = love Thermophiles Thermo = heat
Eubacteria Parasitic heterotrophs (Streptococcus) SaprophagesSapro = death Phage = eat Cyanobacteria (blue-green algae) Photosynthetic Chemosynthetic autotrophs (Rhizobium)
Bacteria are Named by ShapeCocci (ball-shaped) Streptococcus mutans Bacillus (rod-shaped) Clostridium botulinum Spirilli (spiral-shaped) Treponema palladium
Germ Theory of Disease Joseph Lister – Aseptic TechniquesRobert Koch – Germ Theory A specific microorganism causes a specific disease
Do Now: Use your notes and hw 1.What are the 3 shapes of bacteria? 2.What is the function of the capsule? 3.What is a nucleoid?
Taking a Closer Look at Kingdom Eubacteria, Archaea and Viruses
Standard IX- Five and Six Kingdom Classifications (2 questions)
Bacteria. Bacteria Microscopic organisms that are prokaryotes Microscopic organisms that are prokaryotes Make up two kingdoms of the classification system:
Classification and Structure
Bacteria, Viruses, Protists & Fungi
The Birth of Microbiology Kingdom Monera … The Bacteria.
11A. Archaebacteria and Eubacteria share many characteristics but are classified into their own taxa Archaebacteria and Eubacteria share many characteristics.
Organism Traits Within Kingdoms. Archaebacteria Unicellular: made of one cell Prokaryotes: very simple cells that do not have a nucleus and other organelles.
Bacterial Cells Chapter 19.1.
An introduction to bacteria They Are Everywhere. Prokaryotes Prokaryote: Single-celled organism that lacks a true nucleus (also called bacteria) Prokaryote:
Monerans By Hugh Doyle & Geoff Hewer- Candee. Introduction Moneran is the kingdom deals with bacteria This kingdom is divided into BACTERIA and blue-green.
