Bellwork: What do you think this is?

Science Fact of the Day: Hair cannot be easily destroyed by cold, change of climate, water, or other natural forces and it is resistant to many kinds of acids and corrosive chemicals.

Classification: Domains Essential Question: How do biologists classify life on earth? Now that you know why we need to classify organisms and how to name them; we are going to learn about each taxon in detail.

3 Domains Archaea Bacteria Eukaryota 6 Kingdoms Archaebacteria Eubacteria Plantae Fungi Animalia Protista

Unicellular: made of one cell Multicellular: made of two or more cells Autotroph: able to produce its own food Heterotroph: obtains nutrients from its environment or other organisms

Domain BacteriaBacteria

Organisms in the Eubacteria kingdom are unicellular prokaryotes. Prokaryotes do not have a membrane bound nucleus or membrane bound organelles. Eubacteria are found in all habitats. The cell walls of Eubacteria contain the chemical peptidoglycan. Some eubacteria remain independent as single cells and other group into colonies. Eubacteria reproduce asexually through cell division. Some eubacteria are autotrophic, making their own food, and others are heterotrophic, taking in nutrients from their environment. Eubacteria can cause various diseases, from strep throat to Rocky Mountain spotted fever, but they can also be very helpful. Lactobacillus is used to help make foods like cheese and yogurt, and is also present in the human digestive system. Decomposing organic matter and cycling nitrogen are also important functions of eubacteria.

KingdomEubacteriaArchaebacteria Cell Type? (Prokaryote or Eukaryote) Prokaryotic Unicellular or Multicelluar? Unicellular Autotroph or Heterotroph? Autotroph or Heterotroph Cell Wall? Yes, with peptidoglycan Example E. coli

Domain Archaea

Organisms in the Archaebacteria kingdom are unicellular prokaryotes. They have no membrane bound nucleus or organelles in their single celled bodies. Archaebacteria are similar in size and shape to eubacteria. The cell walls of archaebacteria are different from both eubacteria and eukaryotes because they do not contain the chemical peptidoglycan. Like eubacteria, archaebacteria reproduce asexually through cell division. They can also be autotrophic, making their own food, or heterotrophic, obtaining food from their environment, just like eubacteria. Some archaebacteria are extremeophiles, living in extreme environments such as in hot springs, extremely acidic environments, polar seas, and even in extremely salty water.

Walking pneumonia is often the result of a lung infection from a bacterial microorganism called Mycoplasma pneumoniae. Cases of walking pneumonia are most common in the late summer and fall. But infections can occur with no particular pattern throughout the year. And, even though the disease is contagious, it spreads slowly. The contagious period in most cases lasts less than 10 days. Researchers also think it takes prolonged close contact with an infected person for someone else to develop walking pneumonia; still, there are widespread outbreaks every four to eight years. When those outbreaks occur, walking pneumonia can account for as many as one out of every two cases of pneumonia. Symptoms include: Cough that may come in violent spasms but produce very little mucus Mild flu-like symptoms such as fever and chills Sore throat Headache Tiredness Lingering weakness that may persist after other symptoms go away Some people with walking pneumonia may also have an ear infection, anemia, or a skin rash.

Neisseria gonorrhoeae: Gonorrhea Gonorrhea is a sexually transmitted disease (STD) caused by a bacterium. Gonorrhea can grow easily in the warm, moist areas of the reproductive tract. The bacterium can also grow in the mouth, throat, eyes, and anus. Common symptoms in men include a burning sensation when urinating, or a white, yellow, or green discharge from the penis that usually appears 1 to 14 days after infection. Most women with gonorrhea do not have any symptoms. Even when a woman has symptoms, they are often mild and include a painful or burning sensation when urinating, increased vaginal discharge, or vaginal bleeding between periods. Women with gonorrhea are at risk of developing serious complications from the infection, even if symptoms are not present or are mild.complications

Halophiles These are salt-loving bacteria that grow in places like the Great Salt Lake of Utah or salt ponds on the edge of San Francisco Bay. Large numbers of certain halophiles can turn these waters a dark pink. Pink halophiles contain a pigment very similar to the rhodopsin in the human retina. They use this visual pigment for a type of photosynthesis that does not produce oxygen. Halophiles are aerobes and perform aerobic respiration. The waters of Lake Owens in California

Thermus aquaticus: Thermophiles These are bacteria from hot springs and other high temperature environments. Some can grow above the boiling temperature of water. They are anaerobes, performing anaerobic respiration. Thermophiles are interesting because they contain genes for heat-stable enzymes that may be of great value in industry and medicine. An example is taq polymerase, the gene for which was isolated from a collection of Thermus aquaticus in a Yellowstone Park hot spring. Taq polymerase is used to make large numbers of copies of DNA sequences in a DNA sample. It is invaluable to medicine, biotechnology, and biological research. Annual sales of taq polymerase are roughly half a billion dollars.

Treponema pallidum: Syphilis The appearance of a single sore marks the first (primary) stage of syphilis symptoms. The sore appears at the location where syphilis entered the body. The sore is usually firm, round, and painless. The sore lasts 3 to 6 weeks and heals regardless of whether or not a person is treated. Large, raised, gray or white lesions may develop in warm, moist areas such as the mouth, underarm or groin region. Sometimes rashes associated with secondary syphilis are so faint that they are not noticed. Other symptoms include fever, swollen lymph glands, sore throat, patchy hair loss, headaches, weight loss, muscle aches, and fatigue. The symptoms of secondary syphilis will go away with or without treatment. Symptoms of the late stage of syphilis include difficulty coordinating muscle movements, paralysis, numbness, gradual blindness, and dementia. In the late stages of syphilis, the disease damages the internal organs, including the brain, nerves, eyes, heart, blood vessels, liver, bones, and joints. This damage can result in death.
