1. Science form 5 Bab 1 microorganism and their effect on living things
Types of microorganism
Bacteria
Bacteria can be classified based to their shape
A) Coccus - spherical
B) Bacilus - rod shaped
C) Vibrio - comma- shaped
D) Spirillum - spiral shaped
(tuberculosis)
Protozoa
Protozoa is an unicellular animals that are very small
( malaria)

2. Algae
Algae are unicellular or multicellular aquatic plant which have chlorophyll
Virus
Virus are the smallest microorganism and only grow and repriduce in livin cell.
( dengue, hepatitis b , common cold , mumps)
Fungi
Fungi does not have chlorophyll
(tinea, ringworm)

3. Factor can affect the growth of microorganism
Nutrien and humidity
Light
Temeature
Ph
List down the hyothesis and infrence of microorganism
1) Bacteria grow well in dark and bright .
2) Bacteria grow active in temperature 35c and grow inactive at 5c and 70c
3) Bacteria grow well in neutral condition and grow inactive in acidic and alkaline .
Aim of the experiment of microorganism
To study ( ) on the growth of ( )
