The Six Kingdoms

Standard: Organisms are classified into six kingdoms based

on external and internal characteristics

Introduction

Six Kingdoms

-organized according to type of cells, ability to

make food, number of cells in body, how the organism develops

1. Archaebacteria

2. Eubacteria

3. Protists

4. Fungi

5. Plants

6. Animals

Terminology

Getting food

autotrophs – make own food

hetertrophs – get food from other sources

Type of cells

prokaryotic – no nucleus

eukaryotic – with a nucleus

Terminology continued

Body type

unicellular – made of only one cell

multicellular – made of more than one cell;

-have cells with special functions

Reproduction

sexual – need male and female parents

asexual – need only one parent

Archaebacteria

-”ancient bacteria”

-existed before dinosaurs

-live in extreme environments

-hot springs

-acidic environment

-methane

-unicellular prokaryotes

-some autotrophs, some heterotrophs

Eubacteria

Chemical makeup is different from that of archaebacteria.

-unicellular prokaryote

-some autotrophs, some heterotrophs

Protists

-“odds and ends” kingdom because its organisms are pretty different from one another

-most unicellular, some multicellular

-eukaryotes

-some autotrophs, some heterotrophs

Fungi

-mushrooms, mold, and mildew

-most are multicellular, some (like yeast) are unicellular

-eukaryotes

-all are heterotrophs

-eat dead or decaying organisms

Plants

-all plants are multicellular

-all are eukaryotes

-plants are autotrophs

Animals

-all are multicellular

-all are eukaryotes

-all are heterotrophs
