Question 1

fungi

Answer 1

Fungi can be single-celled (such as
yeast) or can invade cells and absorb
their nutrients (such as mould). Fungi
can live on decaying surfaces or in
living tissue.

Question 2

protozoa

Answer 2

Protozoa are single-celled organisms that
are larger than viruses and bacteria.
They absorb nutrients from their
surroundings. Malaria and amoebic
dysentery are caused by protozoa.

Question 3

bacteria

Answer 3

Bacteria are also single-celled organisms
that live between cells. They grow very
quickly under the right conditions.
Bacteria cause diseases as cholera and
pneumonia, and can also lead to food
poisoning.

Question 4

viruses

Answer 4

Viruses can only live inside other cells –
they invade then destroy the cells, and
are responsible for many diseases.

Although technically viruses are not living
things, we still class them to be microorganisms.

Question 5

superbug

Answer 5

A superbug is a particular strain of a
microorganism that has become
resistant to treatments – existing
medications such as antibiotics could
not help the patient.
