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 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?
Bacteria. I. Prokaryotes A.Prokaryotes: single-celled organisms that lack a nucleus 1. Eubacteria – walls contain peptidoglycan (a carbohydrate) 2. Archaebacteria.
Biology AHSGE 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:
Bacterial Cells 1.How is bacteria a part of recycling and biodegrading? It breaks down organic material for plant roots to use 2.Draw the basic appearance.
Bacteria. Cell Type Are they unicellular or multicellular? Are they prokaryotes or eukaryotes? Do they have a cell wall? What type? Explain gram staining.
Bacteria Bacteria. Peptidoglycan Cell wall Cell membrane Ribosome Flagellum DNA Pili Section 19-1 Eubacterium Structure.
Microbiology. Bacteria 1. How many cells? 2. Type of organism? 3. Nucleus? 4. Membrane bound organelles? 5. What kingdom are they in? Unicellular Prokaryotic.
Taking a Closer Look at Kingdom Eubacteria, Archaea and Viruses Objectives: 1. Compare and contrast Eubacteria, Archaea and Viruses 2. Explain why viruses.
Overview of the Six Kingdoms. Vocabulary Which term means one-celled? Many-celled? multicellular multicellular unicellular unicellular Which term means.
All organisms (living things) can be classified into two categories: Unicellular (Single Celled) and Multi- cellular Unicellular organisms are made.
Kingdom Protista. Cell Type Are they unicellular, multicellular, or both? Are they prokaryotes or eukaryotes? Do they have a cell wall? What type? Add.
Kingdoms. Basic Branches of Life More than 200 years ago, Linnaeus began with only the Plant and Animal Kingdoms. Later Kingdoms Protista, Fungi,
Robert Hooke, Anton van Leeuwenhoek, and the invention of the microscopic opened our eyes to the world around us. Microscopic life covers nearly every.
Bacteria Classification Chapter 7 – Section 1. Kingdoms Bacteria are classified into two kingdoms: –Eubacteria –Archaebacteria.
Game Board Let’s Play Jeopardy. Game Board Cell Parts Jeopardy Go to the next slide by clicking mouse. Choose a category and number value clicking on.
Bacteria: Classification and Structure. What are the 6 Kingdoms? Archaebacteria Eubacteria Protists Fungi Plants Animals.
Inside the Cell Plant and Animal. Enter the Cell In our journey through the cell we will see tiny cell structures, called organelles, which carry out.
Chapter 20 Viruses and Bacteria Section 1: Viruses Section 2: Bacteria.
Chapter 19 Bacteria and Viruses Bacteria The invention of the microscope opened our eyes to the hidden, living world around us Microscopic life.
SC.912.L.15.6 Classification. You need to know: 1. The distinguishing characteristics of the domains ( Bacteria, Archae, and Eukarya) and kingdoms of.
Cells. All living things are made up of cells Cells are the building blocks of life Organization Organ Systems Organs Tissues Cells Tissues are made of.
Energy in a Cell Terms Chemosynthetic Organisms that obtain cellular energy by breaking down inorganic chemicals Autotroph creates their own food through.
1 Study of Biology. 2 What is Biology? Biology is the study of all living things Living things are called organisms Living things are called organisms.
Bacteria Our invisible friends. Bacteria are prokaryotes Pro – before Karyon – nucleus The simplest forms of life are prokaryotes. Earths first cells.

Discovery of Cells. First to View Cells In 1665, Robert Hooke used a microscope to examine a thin slice of cork What he saw looked like small boxes so.
Bacteria How Discovered? Draw and label. Describe cell structure and how moves. How obtains food and energy? Explain types of bacteria reproduction. List.
