Organisms The six characteristics common to all living

organisms:

are made of cells obtain and use energy grow and develop

reproduce respond and adapt to the environment

eliminate waste

3 Domains and Six Kingdoms

3 Domains

(the broadest level of classification)

Archaea Prokaryotes that live in extreme environments

Bacteria Prokaryotes that cannot live in extreme

environment

Eukarya Any organism that is a eukaryote

Organisms are made of cells. Single Celled Organisms

(unicellular)

• Whole organism is one

cell.

Multi-celled Organism

(multicellular)

• Organism is complex and

made of many cells.

Diatoms Algae

Bacteria

Which organisms are single celled or unicellular?

Organisms are made of cells.

Eukaryotic Cell

• The cell(s) of the

organism have a

nucleus.

Prokaryotic Cell

• The cell of the organism

does not have a nucleus.

Organisms reproduce

Sexual

Reproduction

• Offspring arise from

the mating of two

parents.

Asexual

Reproduction

• Offspring arise from a

single parent

Organisms obtain and use

energy. Autotrophic Organism

• Organism can produce,

or make, its own food.

• Producer

Heterotrophic Organism

• Organism must consume

other organisms for food.

• Consumer or Decomposer

Which organisms are heterotrophic?

turtle mushroom

Card Sorting

• Scientist classify organisms into groups

according to their________________.

These cards have organisms from each

group. Try to classify the organisms into

groups.

characteristics

Domain: Eukarya

Kingdom: Animalia

Eukaryotic - the cell has a nucleus

Multicellular- made of many cells

Heterotrophic – feeds on others consumers

Sexual reproduction- two parents

Most have symmetrical bodies

Move around on its own- motile

Domain: Eukarya

Kingdom: Plantae

Eukaryotic - the cell has a nucleus

Multicellular- made of many cells

Autotrophic – produces its own food

Sexual or Asexual reproduction

Do not move on their own- sessile

Normal environment

Domain: Eukarya

Kingdom: Fungi

Eukaryotic - the cell has a nucleus

Multicellular

Heterotrophic – eats other organisms

Sexual or Asexual reproduction

Sessile

Normal environment

Domain:Eukarya

Kingdom: Protista Eukaryotic - the cell has a nucleus

Unicellular

Most are Heterotrophic

Primarily Asexual reproduction

Normal environment

Microscopic

Motile

Which Kingdom Protista organism is autotrophic?

Green

algae

Amoeba Paramecium

kelp

Euglena

Domain: Bacteria

Motile

Asexual reproduction (cell division)

Normal environment

Can be found everywhere

Some beneficial

Some are harmful and cause disease

Microscopic.

• Live in extreme environments that are

high in salt, acid or temperature

halophile

thermophile

Domain: Archaea Kingdom: Archaeabacteria

Which Kingdom do

humans belong?

Two Kingdom Classification

1758 • Carolus Linnaeus

• Animals (including protista)

• Plants (including bacteria, fungi).
