Slide1
Describe, in as much detail as you can, the structure of a prokaryotic cell.
Topic: Cells
Define endothermic and exothermic reactions.
Topic: Energy Changes
Name the 3 non contact forces.
Topic: Forces
Describe the physical defences we have to stop pathogens entering our body
.
Topic: Infection and Response
Explain how to calculate the relative formula mass.
Topic: Quantitative Chemistry
Challenge: Briefly describe natural selection
Slide2Learning objectives
Define communicable and non communicable disease with examples
Name some common diseases and the pathogens that cause them
Summarise key features of bacteria and viruses
Summarise key points of some common infections
Slide3Describe what is happening in this image?
You must write
in full sentences

Slide4Communicable and Non-Communicable Diseases: Examples
Can you write a definition for the words communicable and non-communicable, in terms of diseases?
Communicable –
Can be transmitted from one person to the other.
Non-Communicable –
Cannot be transmitted from one person to the other.
Communicable Diseases
Non-Communicable Diseases
measles
mumps
rubella
malaria
cancer
heart attack
diabetes
asthma
Slide5Which type of pathogen is the cause of these diseases?
MeaslesSalmonella
GonorrhoeaAIDSMalaria
Rose Black Spot
Tobacco Mosaic Virus
Virus
Virus
Bacteria
Protozoa
Virus
Bacteria
Fungi
Slide6Pathogens are passed on to other people by a range of different methods; make a list of all the ways that diseases can be spread
Give yourself a mark out of 8Can you name any diseases that are spread by each mode of transmission?
Direct (Physical) contact
Body fluids
Mother to unborn baby
Shared needles/syringes
Air particles
Food
Water
Vector (insects)
Slide7Features of Bacteria: Checklist
They are prokaryotic cells.
They do not have a nucleus (just a circular strand of DNA).
They produce toxins that damage cells and make us feel ill.
The largest bacteria are 10 micrometres long.
Examples: Gonorrhea. Salmonella.
Slide8Slide9Slide10They are
not cells.They are much smaller than bacteria.
They reproduce inside host cells.Once inside a cell, the virus makes many copies of itself. This continues until the cell bursts open. It is this cell damage that makes humans feel unwell.
Measles, HIV and TMV are caused by viruses.
Features of Viruses: Checklist

Slide15Key Words:
Challenge:
Meningitis is spread by droplet infection. Explain how meningitis can be spread by droplet infection.
(2 marks)Droplets containing meningitis are released through coughing and sneezing; these droplets are inhaled and the pathogens infect the next person.
Coronary heart disease (CHD) is a non communicable disease. It is caused by a build up of fatty material in the coronary arteries.
Explain what a non communicable disease is. (2 marks)
is not caused by a pathogen / infective organism
allow not caused by a microorganism / microbe
ignore not caused by infection ignore named pathogen unless bacteria, virus and fungus all mentioned 1 (so) is not passed / spread (from person to person)allow cannot be spread / caughtallow is not infectious / contagious 1

HIV is another sexually transmitted disease.
Explain why prescribing an antibiotic will
not
cure HIV.
