MICRO-ORGANISMS
- All micro-organisms are CONSUMERS, whereas Green Plants for example are producers, meaning they produce there own food. We are also consumers, like all animals, as we cannot produce our own food, instead we eat other organisms. Fungi do not contain chlorophyll so cannot produce their own food
- Micro-organisms are either SAPROPHYTES or PARASITES
- Saprophytes live and feed on dead matter and can be called decomposers
- Parasites live on living organisms
- Microorganisms are divided into: BACTERIA, FUNGI and VIRUS

a) Why must the original petri dishes be sterile
b) Why is the lid left off one dish
c) Why the petri dishes are labelled on the bottom
d) Why are the dishes left in a warm place
e) How can you tell the difference between the different microorganisms growing on the plate
f) What types of microorganisms are growing on the plate and what are the reasons
g) Why was there no growth on the control plate
