THE DOMAINS AND KINGDOMS OF LIFE!

Scientists divide all living organisms into 3 very large groups called domains. CLASS

Scientists divide all living organisms into 3 very large groups called domains. CLASS QUESTION: WHY DO YOU THINK SCIENTISTS MIGHT USE A CLASSIFICATION SYSTEM FOR ORGANISMS?

THE 3 DOMAINS All living organisms can be divided into 3 domains. They are:

THE 3 DOMAINS All living organisms can be divided into 3 domains. They are: Archaea – Living organisms that do NOT have a nucleus Bacteria – Living organisms that do NOT have a nucleus. Eukaryotic – Living organisms with a nucleus in their cells. % of life on Earth by domain Archaea 4% Bacteria 7% Eukaryotic 89%

FUN FACTS! There are estimated to be about 1 million types of bacteria of

FUN FACTS! There are estimated to be about 1 million types of bacteria of which only 4, 000 have been identified! The Archaea have an estimated 600, 000 types of species. In the Eukaryota domain, there about 12. 4 million species!!

THE 6 KINGDOMS There are 6 recognized kingdoms. They are: 1. Archaea 2. Bacteria

THE 6 KINGDOMS There are 6 recognized kingdoms. They are: 1. Archaea 2. Bacteria 3. Protists 4. Fungi 5. Plants 6. Animals

In order to classify living things, we must ask 4 questions! They are:

In order to classify living things, we must ask 4 questions! They are:

1) Does it have a nucleus in its cells?

1) Does it have a nucleus in its cells?

2) Is it unicellular or multicellular?

2) Is it unicellular or multicellular?

3) How does it obtain food? Is the organism autotrophic or Heterotrophic?

3) How does it obtain food? Is the organism autotrophic or Heterotrophic?

4) How does it reproduce? All living organisms reproduce! There are 2 modes of

4) How does it reproduce? All living organisms reproduce! There are 2 modes of reproduction: These are…. .

1. Asexual reproduction is by cell division or by cloning. The main feature here

1. Asexual reproduction is by cell division or by cloning. The main feature here is that offspring (babies) have exactly the same genetic material as the parent! Examples: Archaea and Eubacteria reproduce asexually.

2. Sexual reproduction involves the exchange of genetic material to produce new offspring. Examples:

2. Sexual reproduction involves the exchange of genetic material to produce new offspring. Examples: Plants reproduce using flowers to make egg and sperm cells Animals make egg and sperm cells. Protists simply exchange their information. Fungi can reproduce sexually and asexually.

QUESTION RECAP! What are the 4 characteristics used to determine what kingdom a living

QUESTION RECAP! What are the 4 characteristics used to determine what kingdom a living organism belongs too?

1 – Do they have a Nucleus? 2 – Number of cells? 3

1 – Do they have a Nucleus? 2 – Number of cells? 3 – How the obtain food? 4 – How they reproduce? ANSWER!
