Two Original Kingdoms:

1) Plantae and

2) Animalia

- Discovered single-celled organisms and had to add:

3) Protista

- Then discovered that some single-celled organisms had no true nucleus, so added:

4) Monera

- Then it became evident that fungi were so different from plants that it got it's own kingdom:

5) Fungi

- but things may not be finished, because of the living/non-living debate:

6) ??? Could the next Kingdom be VIRUSES?

They are not cells because they have no metabolic processes

Cannot function as living systems

Reproduction is the only living function they preform

Must invade other cells to reproduce

Act more like parasites of cells

A single virus is known as a viron

Consists of a capsid and a nucleic acid core

May be spiral or many sided in shape

Viruses are very specific in function or infection of organisms

The Importance of Microbes:

- decompose dead plant and animals

- without microbes, materials would be locked up in the surrounding environment

- microbes convert and recycle elements like carbon, oxygen, sulfur and nitrogen into nutrients for plants and animals

the study of microbes or microorganisms is called Microbiology, which has become one of the three major branches of biology ( Zoology and Botany)
this field of study is used to develop new medicines

The FIVE Kingdoms

Always order them from smallest, less complex to highest order of complexity in terms of biology.
