Microorganisms

Standard: 8.L.1.1 & 8.L.1.2

Explaining microbiology

Microbiology is the study of microscopic organisms, such as bacteria, viruses, archaea, fungi and protozoa.

Virus

Viruses are non-living organisms that are small; Disease producing particles; They are unable to reproduce without a host

Bacteria

Bacteria is microscopic, single celled, prokaryotic microorganisms that live freely in soil, water, or inside living things and reproduce rapidly.

Fungi

Fungi is a diverse group of eukaryotic organisms that live by decomposing the organic material in which they grow. Ex: Mushrooms, mildews, and yeasts.

Parasites

Parasites are organisms that live on or inside of another organism and benefits by taking nutrients from its host.

Outbreaks, Epidemics, and Pandemics!

Outbreaks are the occurrence of a disease greater than would otherwise be expected at a particular time and place.


Epidemics are an outbreak of a disease that affects many people in an area of a specific country or region.


Pandemics are an epidemic that spreads over a very large area or throughout the entire world.
