Microorganisms, genetic 4 Name four causes of disease in information, lifestyle and humans: environment Microscope 5 Name the piece of equipment used to view cells in detail. CHALLENGE: Explain why bacteria are a prokaryotic organism.  Prior Today Leads to Knowledge Learning Intention: Learning Intention: What are pathogens Describe how Explain the difference Recall the four types of pathogens can be pathogens between viruses and spread bacteria Pathogens, viruses, bacteria  Key word Pathogen Pathogens are Bacteria, viruses, microorganisms that fungi and protists cause disease are examples of pathogens Show me…… 1) Good bacteria is classed as a pathogen 2) All bacteria are pathogens 3) Only bacteria that causes disease is a pathogen Activating prior knowledge: Pathogens Virus Bacteria fungus Protists  Activation & check of prior knowledge: A pathogen is a microorganism that causes disease TRU All bacteria are pathogens E FAL Covid-19 is an infectious disease so is caused by a SE pathogen TRU Coronary heart disease can be caused by smoking. E Cigarette smoke is a pathogen Cystic fibrosis is a disease that can be inherited from your parents at birth. The gene that causes cystic fibrosis is a type of pathogen CHALLENGE: Explain why any statements you have marked as false are incorrect  What are pathogens? Some young people are discussing pathogens. 1. Who do you agree with? 2. Who do you disagree with, and why? Connor Bacteria and Amelia Freya viruses are ‘Pathogens’ is the pathogens. All pathogens are scientific word for microorganisms. ‘germs’. Jayden All diseases are caused Yasmin by pathogens. Different diseases are caused by different types of pathogens. Lawrence All pathogens are the same. CHALLENGE: Justify why you agree with any person. Pathogens can be spread between organisms in three main ways – through air - Through direct contact (touching) - Through water Disease Pathog Transmission symptoms 1. Name three diseases en type caused by viruses Measles, TMS, HIV Measles virus Drop lets in air Fever and rash 2. Which disease is caused Salmonella Bacteria Direct contact Fever & by a protist? (eating) vomiting Malaria 3. Which diseases are HIV virus Direct contact Flu like transmitted via the air? (body fluids) fever, Measles, TMS attacks 4. Which diseases are immune system spread by direct contact with HIV,bodily fluid? gonorrhoea Malaria protist Direct contact fever (mosquito bite) 5. Which three diseases Measles, cause fever? Gonorrhoea bacteria Direct contact Green salmonella, HIV (body fluids) discharge 6. What diseases are caused (TMS) virus air Discolours salmonella, by bacteria Tobacco plant leaves gonorrhoea mosaic Nodiseases 7. Do – they effect only effect Viruses  Bacteria are prokaryotes – they are living things because they are made of cells.  Bacteria also reproduce very quickly inside the human body.  Many bacteria are helpful to us but some bacteria are pathogens.  Bacteria that are pathogens produce toxins inside tissues.  Toxins are chemicals that damage body tissues making us sick  this diagram shows a bacteria inside the body releasing toxins which cause us to feel ill by damaging cells. Toxins  Viruses Bacteria Live and reproduce inside of cells Live and reproduce Live and reproduce inside of cells outside of cells Live and reproduce Cause damage to Produce toxins outside of cells cells and for them to burst Produce toxins Are not alive Are a living organism Cause damage to cells and for them to burst Reproduce quickly Are a living organism Are not alive Reproduce quickly CHALLENGE: Predict why it is harder to treat viruses with drugs compared to  What are pathogens? The statements are about different pathogens. Viruses reproduce inside body cells TRU Bacteria and viruses are not alive E FAL Viruses produce toxins which damage body tissues SE FAL Bacteria and viruses both reproduce rapidly inside SE the human body TRU All bacteria are pathogens EFAL SE CHALLENGE: Explain why any statements you marked as false are incorrect.  Complete first: Complete once checked blue box Communicable diseases (can / cannot) answers: 1. What do we call diseases that are be transmitted between organisms by spread by a pathogen? (pathogens / inheritance). A Communicable diseases pathogen is a microorganism which 2. What is a pathogen? (infectious) causes (infectious / genetic) diseases. A microorganism that Pathogens can be viruses, bacteria, 3. What causestype of pathogen lives and disease fungi or protists. Pathogens can be reproduces inside living cells? (inherited / spread) between viruses organisms by air, water or direct 4. How do some bacteria damage content. tissues? Produce toxins (viruses / bacteria): live and reproduce inside cells, causing cell damage. Viruses (are / are not) alive. (Viruses / bacteria): may produce toxins that damage tissues and make us feel ill. CHALLENGE: Describe the structure of a bacteria cell Independent Practice
