4.8.1 (D)
What does unicellular mean?
Uni = 1
Cellular = cells
IE One celled organism. All it needs to sustain life is contained in one cell. (Bacteria)
What does multicellular mean?
Multi= multiple
Cellular= cells
IE the organism has many different cells which specialised in a different functions. E.g. heart cells, skin cells and blood cells.(kangaroo)

4.8.3 unicellular organisms
Discuss in groups what could be beneficial and harmful effects of microorganisms on living things and the environment. The following websites can be used.

Human Body
The human body is made up many systems that work together to maintain our bodies. These systems are:

Create a table for each system identifying their main components and their function
Determine what would happen if a system was removed, and show results in a mind map. E.g.
Digestive system removed
Functioning
Human Body
Circulatory

Respirator y system
Skeletal system removed
Excretory system removed
