This document discusses microorganisms and their role in health and illness. It describes how microorganisms can cause infectious diseases through bacteria, viruses, and fungi. Examples are given of harmful diseases caused by cholera bacteria, typhoid fever bacteria, tuberculosis bacteria, and ringworm fungi. The document also notes that the human body contains many beneficial microorganisms as part of its normal microbiome in places like the skin, nose, stomach, and intestines that protect against harmful microorganisms and support health. Beneficial fungi like Penicillium are also mentioned.

11. Virus
 They depend on other organisms to multiply
infect cells Multiply more virus

12. Fungi
 Grow in damp areas
 There are - Unicelular e.g.:
yeast
-Multicelular e.g.:
mushrooms
 They absorb nutrients from
decomposing plants and animals
