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?
Where do we find bacteria?
Review What is a prokaryote? –Cells without membrane bound nucleus –Most surrounded by a cell wall –Many secrete a slime capsule- protection –Lack organelles
How big is a prokaryotic cell? 1-5 micrometers A micrometer, also written µm, is one thousandth of a millimeter - it's 10 -6 m.
Classification of Prokaryotes Eubacteria –Surrounded by a cell wall containing peptidoglycan Example: Rhizobium
Classification of Prokartyotes Archaebacteria –Surrounded by a cell wall lacking peptidoglycan Example: Methanogen
How do we identify Prokaryotes? 1.Shape Three groups: 1.Coccus: spherical 2.Bacillus: rod shaped 3.Spirillum: spiral
Motility Flagella Slime secretion Spiral motion
Obtaining energy Autotroph –Makes own food Heterotroph –Ingests nutrients
1.photoautotroph Carry on photosynthesis
2. chemoautotroph Gain energy from inorganic molecules
3. Photoheterotrophs Photosynthesis AND ingestion of organic compounds
Obligate aerobes –Require oxygen Obligate anaerobes –Must live in the absence of oxygen Facultative anaerobes –Can live with or without oxygen
Exit ticket What are the three types of movement for bacteria cells? Give an example of Eubacteria. Give an example of Archaebacteria. What are the three different ways bacteria can obtain energy?
Identifying and Classifying Bacteria Ch. 23. What is a prokaryote? Cells that lack a true nucleus. Cells that lack a true nucleus. Cells that lack membrane-
Identifying and Classifying Bacteria. What is a prokaryote? Cells that lack a true nucleus. Cells that lack a true nucleus. Cells that lack membrane-
Chapter 19. Eubacteria Are prokaryotes – have no membrane bound nucleus The larger of the 2 kingdoms Live almost everywhere Fresh water, salt water, land,
Bacteria What you need to know!!!!. What are Bacteria? They are prokaryotes that have cell walls containing peptidoglycans. Prokaryotes: Organisms who’s.
KINGDOM MONERA. Monerans The most successful organisms on earth Longevity - bacteria have been around for 4 billion years Bacteria can reproduce every.
Virus & Bacteria Unit. Part 1: Viruses Big Idea: VIRUSES ARE NOT LIVING BECAUSE THEY DON’T FULFILL ALL THE CHARACTERISTICS OF LIVING THINGS.
Domain Archaea Kingdom Archaebacteria. Phyla Crenarchaeota Euryarchaeota Korarchaeota Nanoarchaeota Thaumarchaeota.
Archaebacteria: bacteria that lacks the peptidoglycan layer in its structure- Older (in time) bacteria ◦ Live in oxygen free environment ◦ Produce.
And Bacterial Creepers I study the lives on a leaf:the little Sleepers, numb nudgers in cold dimensions Beetles in caves, newts, stone-deaf fishes, Lice.
Bacteria Kingdoms Archaebacteria and Eubacteria. Bacteria are known in two types: Ancient Bacteria – Archaebacteria True Bacteria – Eubacteria They are.
Bacteria. I. Prokaryotes A.Prokaryotes: single-celled organisms that lack a nucleus 1. Eubacteria – walls contain peptidoglycan (a carbohydrate) 2. Archaebacteria.
Bacteria and Viruses Chapter 19. Introduction Microscopic life covers nearly every square centimeter of Earth. In a single drop of pond water you would.
Chapter 18. Domain Archaea Only one kingdom: Archaebacteria ▪ Cells contain cell walls ▪ Live in extreme environments (hot, acidic, salty, no O 2.
BACTERIA KEY CONCEPTS. 1. LIVING UNICELLULAR ORGANISMS 1. LIVING UNICELLULAR ORGANISMS 2. PROKARYOTIC = NO NUCLEUS 2. PROKARYOTIC = NO NUCLEUS CONSISTS.
Chapter 18 Bacteria. Section Concept Map are classified into the kingdoms of live in harsh environments such as include a variety of lifestyles.
An introduction to bacteria They Are Everywhere. Prokaryotes Prokaryote: Single-celled organism that lacks a true nucleus (also called bacteria) Prokaryote:
Bacteria. Bacteria Microscopic organisms that are prokaryotes Microscopic organisms that are prokaryotes Make up two kingdoms of the classification system:
5 Kingdom System vs. 3 Domain System Previously the diversity of life was classified based on 5 kingdoms 1.Monera (prokaryotes) 2.Protists (simple eukaryotes)
Chapter 19 Bacteria and Viruses. I. Prokaryotes A.Prokaryotes: single-celled organisms that lack a nucleus 1. Eubacteria – walls contain peptidoglycan.
Bacteria. Kingdom Archaebacteria Prokaryotes Single celled Cell Wall (does not have peptidoglycan) Live in harsh environments 3 major groups 1) methanogens.
Five-Kingdom Survey Taxonomy – Categories called taxa (singular = taxon) Kingdom Phylum Class Order Family Genus Species.
Biology AHSGE Standard IX- Five and Six Kingdom Classifications (2 questions)
BACTERIA NOTES Bacteria The smallest and most common microorganisms are prokaryotes— unicellular organisms that lack a nucleus. Earliest fossils.
Prokaryotes: Bacteria. Bacteria Found on almost every square cm of Earth Bacteria = prokaryotes –Remember: no nucleus and no membrane bound organelles.
The 6 Kingdoms. Classification Domain (recent addition)-Kingdom- Phylum - Class- Order- Family- Genus- Species 3 Domains Archaea Archaea Bacteria.
Prokaryote Microorganisms 11.0 Classify animals according to type of skeletal structure, method of fertilization and reproduction, body symmetry, body.
Bacteria Chapter 20 Sections 1. What Are Prokaryotes? Single-celled organisms that do not have membrane-bound organelles Found in 3 shapes: Bacillus.
Bacteria Quick Fact – Used to be in the Kingdom Monera – 1 kingdom, now they are in 2 separate kingdoms and 2 separate domains. Remember: New discoveries.

Chapter 27~Prokaryotes and the Origins of Metabolic Diversity.
Structure and Function of Bacteria. Kingdom Archaebacteria Extreme environments Methanogens – Make methane gas, anerobic Halophiles – salt loving, use.
BACTERIA Structure, Function, Reproduction, and Growth.
PROKARYOTE Bacteria. Two Types Eubacteria Live in many places Cell wall protects and gives shape Peptidoglycan Archaebateria No peptidoglycan.
End Show Slide 1 of 40 Biology Mr. Karns Bacteria.
WARM UP Wednesday, March 20, 2013 Which process creates a protein (RNA to protein)?
BACTERIA Unicellular Organisms Prokaryotes (no true nucleus)
Bacteria. Bacteria differ from Eukaryotes No nucleus or membrane bound organelles 10 times smaller Unicellular, activities not specialized Single chromosome.
Prokaryotes Chapter 27. Slide 2 of 20 Kingdom Monera Prokaryotes Unicellular (Single-celled) organisms that lack membrane-bound organelles and nuclei.
Prokaryote: no nucleus –Chromosome & plasmids float freely in cytoplasm Ribosomes: create proteins Flagella: used in movement Pili: act as anchors Capsule:
Daily Questions 1. What is the difference between binary fission and conjugation? 2. What are obligate anaerobes? 3. Archaebacteria belong to the domain.
Biology 112 BACTERIA AND VIRUSES. Smallest and most common microorganisms Unicellular organisms that lack a nucleus They can be divided into two.
Chapter 27~ Prokaryotes and the Origins of Metabolic Diversity.
1 Bacteria Domain: Bacteria and Archaea Kingdom Eubacteria and Archaebacteria (previously Monera) Crash Course: Bacteria Video.
PAP Bacteria and Virus Notes Ch 19. Bacteria are grouped into two kingdoms: -Eubacteria and Arcahebacteria -Eubacteria and Archaebacteria have different.

Bacteria Ch.19-1 By: A. Cortez. Classifying Prokaryotes Thanks to Robert Hooke and Anton van Leeuwenhoek, the invention of the microscope opened our eyes.
Monerans: Bacteria Friend or Foe. Prokaryotes Bacteria = Prokaryotes Bacteria = Prokaryotes Discovered when Robert Hooke and Anton van Leeuwenhoek invented.
Bacteria. Prokaryotes Single-celled organisms that lack a nucleus, usually very small Also known as bacteria.
Marconi Bacteria consist of only a single cell, but don't let their small size and seeming simplicity fool you. They're an amazingly complex and.
