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
Kingdom: Eubacteria
Prokaryotic - the cell has NO nucleus
Unicellular- made of one cell
Heterotrophic
Motile
Asexual reproduction (cell division)
Normal environment
Can be found everywhere
Some beneficial
Some are harmful and cause disease
Microscopic.
spirilla
bacilli
cocci cyanobacteria
cyanobacteria
Domain: Bacteria Kingdom: Eubacteria
Domain: Archaea
Kingdom: Archaeabacteria
• Prokaryotic- no nucleus
• Unicellular
• Heterotrophic or Autotrophic
• Asexual reproduction
• 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).
The Five Kingdom classification
1940 Lynn Margulis
3 Domains and Six Kingdoms 1990
