What characteristics
could scientists use
to sort (classify)
living organisms?
1) The number of cells
Unicellular
(one)
/
Multicellular
(more than one)
2) If it has a nucleus
X
X
Eukaryotic / Prokaryotic
(true)
(no)
3) The method of obtaining food
4) The ability to move

3 Domain system
Bacteria no nucleus,
normal environments
Archaea no nucleus,
extreme environments
Eukaryotes has a
nucleus

Time to take notes!!!!
Pg. 43
Remember:
Eukaryotic = nucleus
Prokaryotic = no nucleus
Cell Type
Eukaryotic
Cell Wall?
No
# of Cells
Multi-cellular
Obtain food
Consume it!
Movement
Most are mobile
Reproduction
Sexual or Asexual
(depends on organism)
Fun Fact
•Found within most habitats
•Require oxygen
•Maintain homeostasis
Fun Fact! Carvings in tree
stems will not move!
Cell Type
Eukaryotic
Cell Wall?
Yes
# of Cells
Multicellular
Obtain food
Photosynthesis
Require: Oxygen, Carbon Dioxide, Water, Minerals (from soil)
Movement
Non-mobile
Plants will grow toward light, leaves move
Reproduction
Sexual /Asexual
Fun Fact
Plants are found virtually everywhere
Except: Arid deserts, arctic, deep ocean
Cell Type
Eukaryotic
Cell Wall?
Yes
# of Cells
Mostly Multicellular
Obtain food
Decomposers
Organic Compounds (plants and animals)
Movement
Non-mobile
BUT cells can move as a team
~Through hyphae
“Grow to get food”
Reproduction
Sexual or Asexual (spores)
Fun Fact
Fun Facts! The largest fungus is 2,200 acres big!
It takes 50-100 years for fungi to
decompose a tree

Cell Type
Eukaryotic
Cell Wall?
Some have, some don’t
# of Cells
Unicellular or Multicellular
(but they don’t have specialized tissue!)
Obtain food
Photosynthesis/Engulfing
Organic Compounds (plants and animals)
Movement
Flagella
Cillia
Pseudopods – False foot
Non-Mobile
Reproduction
Sexual or Asexual (spores)
Fun Fact
Must live in liquid (water)
There are 60,000 types!

There are a couple of other brainpops about the different
types of protists. You are welcome to search around for them,
but they aren’t required.
Cell Type
Prokaryotic
Cell Wall?
Yes
# of Cells
Unicellular
Obtain food
Use organic compounds
(normal stuff)
Movement
Flagella
Tumbling
Re-arranging cytoskeleton
Reproduction
Asexual (Binary Fission)
Fun Fact
They live in every normal habitat on earth – even in
YOU!!
There are 10x more bacteria cells in your body right now
than human cells!
Cell Type
Prokaryotic
Cell Wall?
Yes
# of Cells
Unicellular
Obtain food
WIDE RANGE!!! (weird stuff!)
Inorganic compounds, Ammonia,
Metal Ions, Hydrogen, Gas
Movement
Flagella
Reproduction
Asexual (Binary Fission)
Fun Fact
They live in EXTREME habitats!
Halophiles (high salt), Acidophiles,
Thermophiles, Alkaliphiles, even on Mars??
Cell Type
Prokaryotic
Cell Wall?
Yes
# of Cells
Unicellular
Obtain food
Photosynthesis
Decompose (plants and animals)
Use elements (nitrogen, hydrogen, sulfur)
Movement
Flagella
Tumbling
Re-arranging cytoskeleton
Reproduction
Asexual (Binary Fission)
Fun Fact
They live in every habitat on earth – even in YOU!!
There are 10x more bacteria cells in your body right now than human cells!
