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

THE DOMAINS AND KINGDOMS OF LIFE!

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: 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 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 3. Protists 4. Fungi 5. Plants 6. Animals

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

1) Does it have a nucleus in its cells?

2) Is it unicellular or multicellular?

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 reproduction: These are…. .

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: 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 organism belongs too?

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

GUESS WHO GAME? 6 KINGDOMS! On the next few slides, try to guess which kingdom the facts are referring to!

I am made of many cells. My cells have an organized nucleus. I have two parents and eat food! Guess Who?

Animalia

I can make my own food, but sometimes I also eat food. I can have 1 or 2 parents. My cells have a nucleus. I usually have 1 cell, but sometimes more! Guess Who?

Protists

I can make my own food but sometimes eat food. I am unicellular. I have one parent and I do not have a nucleus. Sometimes I cause diseases and other times I am a decomposer. Guess Who?

Bacteria

I am made of many cells. My cells have an organized nucleus. I mostly have 2 parents, but sometimes 1. I make my own food. Guess Who?

Plantae

My cells have a nucleus and I am usually made of many cells. I cannot make my own food so I must eat. I can have 1 or 2 parents. Guess Who?

Fungi

I am unicellular with no nucleus. I have only 1 parent. I can be both autotrophic and heterotrophic. I like to live in volcano vents, salt water of deep oceans or the freezing cold arctic. Guess Who?

Archaebacteria
