| Microbe | An organism that can only be seen through a microscope |
| Gastrointestinal | Related to the stomach and intestines |
| Infection | The growth of germs in your body |
| Organelle | A specialized structure in a cell |
| Chloroplast | Organelle that contains the green pigment chlorophyll uses in photosynthesis |
| Bacteria | The most common form of one-celled organisms |
| Metabolism | The combination of chemical reactions that takes place in an organism; food is converted into energy that the organism uses to carry out its life processes. Colony: A group of only one kind of bacteria that grows from a single original bacterium. |
| Case Study | An observation of a person or group to use as a model |
| Microbiology | The study of microorganisms |
| Agar | A jelly-like substance that contains the nutrients bacteria need to grow |
| Infectious Agent | Something that can get inside your body, multiply, and cause disease |
| Types Of Germs | Bacteria & Viruses (Rods, Spheres, Spirals) |
| Ways to Reduce Spread Of Germs | Washing Hands, Cutting Meats and Veggies on Different Cutting Boards, Sneezing into Arm or On Tissue, Avoid Touching Face |
| How Do Germs Relate To Food Handling | Cutting Meats and Veggies on Different Cutting Boards, Storing Food in Cold Places Because Bacteria Reproduces Quickly in Warm Places |
| Cell Theory | All living things are composed of cells, Cells are the basic units of structure and function in living things, and All cells are produced from other cells |
| Parts- Differences Between Plant and Animal Cells | Animal & Plant- Nucleus, Cytoplasm, Cell Membrane, Mitochondria, Vacuole, Chromosomes Plant- Chloroplast, Cell Wall |
| Dependent/Responding Variable | The event studied and expected to change when the independent variable is changed |
| Independent/Manipulated Variable | A variable that is intentionally changed to observe its effect on the dependent variable |
| Similarities/Differences Between Viruses and Bacteria | Similarities-Both are microscopic, Both can cause sickness in other organisms Differences- Viruses reproduce by putting their DNA into the cells of a host, Bacteria reproduce by splitting in half and making two new bacteria |
| Viruses (Characteristics) | Characteristics- Need a Host to Survive, Many Different Types, Some Only Affect Plants, Some Animals, Some Bacteria |
| Viruses (Reproduction) | Can Only Reproduce inside Cells, Each Virus has a Different way to Reproduce |
| Viruses (Spread) | Same way Bacteria are Spread, Droplet Transmission- Sneezing, Coughing, Talking, etc., Contact with Open Sores |
| Eradicated Diseases | Smallpox, Polio |
| Common Cold | Symptoms- Discomfort (Not as much as Flu), Cause other diseases Causes Of- Rhinovirus, Spread by Droplet Spread |
| Polio | Symptoms- Minor to severe muscle weakness, and paralysis Causes Of- Poliomyelitis, Spread by feces, hand to mouth |
| Smallpox | Symptoms- Small itchy spots, High fever, Death Causes Of- Variola Virus, Spread by saliva droplet spread or direct contact with sores |
| Chickenpox | Symptoms- Scratchy itchy spots on body, fever, headache Causes Of- Varicella Virus, Spread by Droplet spread |
| E. Coli | Symptoms- Diarrhea, Fever, Cramps, Vomiting, Nausea Causes of- Food-borne illness, feces |
| Mononucleosis | Symptoms- Tiredness, Headache, Swollen and Stiff Neck, Not feeling hungry, Fever, No drainage from nose, White patches on back of throat Causes of- Spread by Kissing, Coughing, Sneezing, Sharing a Glass, Sputum coughed up |
| Pneumonia (Bacterial) | Symptoms- Inflammation of the lungs, Air sacs in lungs filled with pus, Death, Bad coughs, Chills, Chest pain, Sputum Caused by- Bacteria working their way into your lungs when your body defenses are lowered |
| Pneumonia (Viral) | Symptoms- Fever, Dry Cough, Headache, Muscle pains, Weakness, Increasing breathlessness, Bluish lips Caused by- Viruses invading lungs and multiplying, Almost no physical sign of lung tissue filling with fluid |
| Lyme Disease | Symptoms- Sore spot on leg: bull's-eye, Fever, Headache, Muscle ache Caused by- Ticks |
