Microorganiams that enter the body and cause disease 1 of 37 What are Communicable diseases? Diseases that can spread easily 2 of 37 What is Bacteria? Very small cells which can reproduce rapidly inside your body 3 of 37 How can Bacteria make you feel ill? By producing toxins that damage your cells and tissues 4 of 37 How can Pathogens be spread? Water, Air, Direct Contact 5 of 37 What are 3 examples of viral diseases? Measles, HIV, Tobacco Mosaic Virus 6 of 37 What are some facts about Measles? It is spread by droplets from an infected person's sneeze or cough. Will develop a red skin rash and fever. 7 of 37 What are some facts about HIV? Spread by sexual contact or by exchanging bodily fluids. Causes flu-like symptons. Attacks the immune cells. 8 of 37 What are some facts about Tobacco Mosaic Virus? Affects many species of plants. Causes parts of leaves to become discoloured. Means plants can't carry out photosynthesis well 9 of 37 What is an example of Fungal disease? Rose Black Spot 10 of 37 What are some facts about Rose Black Spot? Causes purple or black spots todevelop on leaves or roses. Means photosynthesis can't happen. 11 of 37 What is an example of a disease called Protist? Malaria 12 of 37 What are some facts about Malaria? It is spread by mosquitos when picking the disease up. It can be fatal 13 of 37 What are 2 examples of Bacterial Diseases? Salmonella, Gonorrhoea 14 of 37 What are some facts about Salmonella? A type of bacteria that causes food poisoning. Can suffer from fever, stomach cramps, vomitting and diarrhoea. Caused by contaminated food. 15 of 37 What are some facts about Gonorrhoea? Sexually Transmitted Disease, Painful when urinated , Treated with antibiotic called pencillin. 16 of 37 How can th spread of disease be reduced or prevented? Hygiene, Destroying Vectors, Isolating Infected Individuals, Vaccination 17 of 37 What are some of the body's defence system? Skin, Hair and Mucus in nose, Trachea and bronchi, Stomach 18 of 37 How does the Immune system attack Pathogens? White Blood cells consume them and produce antibodies and antitoxins 19 of 37 What are the Positives of Vaccination? Help control communicable diseases, Can prevent big outbreaks of disease 20 of 37 What are the Negatives of a Vaccination? Don't always work, Bad reaction is possible but rare 21 of 37 What are the 3 main stages in Drug Testing? Drugs are tested on human cells and tissues, Then teted on live animals, Then tested on human volunteers 22 of 37 What is Aspirin? Used as a painkiller and to lowwer fever. It was developed from a chemical found in Williw 23 of 37 Where does Photosynthesis take place? Chloroplasts 24 of 37 What is the Word Equation for Photosynthesis? Carbon Dioxide * Water - Glucose * Oxygen 25 of 37 What is the Symbol Equation for Photosynthesis? 6CO2 * 6H20 - C6H126 * 6O2 26 of 37 Why do plants use Glucose? Respiration, Making Cellulose, Making Amino Acids, Stored as Oils or Fats, Stored as Starch 27 of 37 What affects the rate of Photosynthesis? Intensity of Light, Concentration of CO2, Temperature, Chlorophyll 28 of 37 What is Respiration? The process of transferring energy from glucose which goes on in every cell 29 of 37 What is an Endothermic Reaction? Absorbs heat and cools surroundings 30 of 37 What is an Exothermic Reaction? Releases heat which causes surroundings to rise in heat 31 of 37 What is Aerobic Respiration? Respiration using Oxygen 32 of 37 What is the Word Equation for Aerobic Respiration? Glucose * Oxygen - Carbon Dioxide * Water 33 of 37 What is the Symbol Equation for Aerobic Respiration? C6H12O6 * 6O2 - 6CO2 * 6H20 34 of 37 What is Anaerobic Respiration? Respiration without Oxygen 35 of 37 What is the Word Equation for Anaerobic Respiration in Muscle Cells?
