The Six Kingdoms

When Linnaeus developed his
system of classification, there were only two kingdoms, Plants and Animals. But the use
of the microscope led to the discovery of new organisms and the
identification of differences in cells.
A two-kingdom system was no
longer useful.

 

Today the system of
classification includes six kingdoms.

The Six Kingdoms:

Plants, Animals, Protists, Fungi, Archaebacteria,
Eubacteria

Plants and Animals

How are organism placed into their kingdoms?

      
Cell type,
complex or simple

      
Their ability to
make food

      
The number of
cells in their body

Plants

You are probably quite
familiar with the members of this kingdom as it contains all the plants that
you have come to know – flowering plants , mosses,
and ferns.Plants are all multicellular and consist of complex
cells.

 

 

In addition plants are autotrophs,
organisms that make their own food.

 

 

With over 250,000 species,
the plant kingdom is the second largest kingdom.Plant species range from the tiny
green mosses to giant trees.

Without
plants, life on Earth would not exist!
Plants feed almost all the heterotrophs (organisms that eat other
organisms) on Earth.Wow!

 

Animals

The animal
kingdom is the largest kingdom with over 1 million known species.

Chordata, Class Mammalia, Order Carnivora, Family Felidae, Genus Pathera, Species tigris

All animals consist of many
complex cells. They are also heterotrophs.

 

Members of the animal kingdom are found in the most
diverse environments in the world.

Archaebacteria

In 1983, scientists tool
samples from a spot deep in the
Pacific Ocean
where hot gases and molten rock boiled into the ocean form the Earth�s
interior.To their surprise they
discovered unicellular (one cell) organisms in the samples. These
organisms are today classified in the kingdom, Archaebacteria.

 

Archaebacteria are
found in extreme environments such as hot boiling water and thermal
vents under conditions with no oxygen or highly acid environments.

 

Finding
Archaebacteria
:
The hot
springs
of Yellowstone
National Park
, USA
, were
among the first places Archaebacteria were discovered. The biologists pictured
above are immersing microscope slides in the boiling pool onto which some
archaebacteria might be captured for study.

 

Eubacteria

Like archaebacteria, eubacteria are complex
and single celled.
Most bacteria are in the EUBACTERIA
kingdom. They are the kinds found everywhere and are the ones people are most
familiar with.

 

Salmonella enteriditis

 

Eubacteria are classified in
their own kingdom because their chemical makeup is different.

Most
eubacteria are helpful.Some produce
vitamins and foods like yogurt.
However, these eubacteria, Streptococci pictured above, can give you
strep throat!

Fungi

Mushrooms, mold and mildew
are all examples of organisms in the kingdom fungi .

 

Most fungi are multicellular and consists of many complex cells.

 

Fun Facts about
Fungi

short description of image

 

Some fungi taste great and others can kill you!

 

Fungi are organisms that biologists once confused
with plants, however, unlike plants,
fungi cannot make their own food.
��
Most obtain their food from parts of plants that are decaying in the
soil.

 

Protists

Slime molds and algae are
protists.

Sometimes they are called
the odds and ends kingdom because its members are so different from one
another. Protists
include all microscopic organisms that are not bacteria, not
animals, not plants and not fungi.

 

 

 

Most protists
are unicellular. You may be
wondering why those protists are not classified in the Archaebacteria or
Eubacteria kingdoms.

 

It is because, unlike
bacteria, protists are complex cells.

 

These delicate looking diatoms are classified in the
protist kingdom.
