Micro-organisms
  • What are micro-organisms?
  • Micro-organisms are very tiny living things. They
    are so small that you need a microscope to see
    them.
  • Viruses, bacteria and fungus are all types of
    micro-organism. Micro-organisms that cause
    diseases are often called germs.
  • Micro-organisms are all around us, in the air, in
    our bodies and in water. Some micro-organisms are
    harmful to us, but others are helpful to us.

Harmful micro-organisms
  • Some diseases, like chickenpox, are caused
  • by viruses. Diseases caused by viruses usually
  • spread easily from one person to another.
  • Uncooked foods (especially meat) can contain
  • bacteria. The bacteria are killed when the
  • food is cooked properly. But if you eat food
  • that has not been cooked properly, the
  • bacteria may survive and make you feel very
  • ill.
  • Mold is a type of micro-organism that grows
  • on decaying food. It can make you ill if you eat
  • it.

LET US RECAP.
  • What are the three Harmful Micro Organisms?

Harmful micro-organisms
  • HOW CAN YOU AVOID SPREADING HARMFUL
  • MICRO-ORGANISMS?
  • You can avoid spreading harmful micro-organisms
    by
  • washing your hands before eating, after preparing
    food and after using the toilet.
  • covering your mouth when you cough or sneeze.
  • keeping away from other people if you have a
    disease that is easily spread.
  • not eating food which is not fresh or has not
    been cooked properly.
  • keeping uncooked meat separate from other foods
    in the fridge.

Helpful micro-organisms
  • Here are some examples of helpful
    micro-organisms.
  • When bread is made, a micro-organisms called
    yeast is
  • added to the dough to make the bread rise.
  • Yogurt is made by boiling milk and adding special
  • bacteria to it. The bacteria turn the sugar in
    the milk into
  • acid. The acid makes the milk go thick and stops
    any
  • harmful bacteria growing.
  • Inside a pile of dead leaves are millions of tiny
    bacteria.
  • These bacteria feed on the leaves and break them
    down
  • into nutrients. The nutrients go back into the
    soil where
  • they can be used by plants.
