PROTISTA
Kingdom Protista
• FUNGUS-LIKE PROTISTS… The slime molds
and water molds
• PLANT-LIKE PROTISTS……. The Algae
• ANIMAL LIKE PROTISTS…. The protozoa
SLIME MOLD… a fungus-like protist
Yellow slim mold… a colony of
thousands of single celled amoeba like
Are you smarter than a slime mold?
More slime mold
Pretzel Slime Mold
Slime mold recreates rail-lines and
interstate highways when grown on a map
Water Mold… a fungus-like protist
Water Mold… not a fungus… a protist
ANIMAL-LIKE PROTISTS
( Protozoans )
This amoeba is about to “eat” the algae cells.
Amoebas are single celled “animal-like” protists
An amoeba has a EUKARYOTIC cell
(cell with a nucleus and many organelles )
WHY is an Amoeba NOT a bacteria?
BACTERIA CELL

No nucleus
No mitochondria
No E.R.
No Golgi apparatus
No vacuoles
Has a nucleus
Has mitochondria
Has E.R.
Has Golgi apparatus
Has vacuoles
Death by Amoeba: Some twin cities youth lost their
lives to an amoeba which infected their brain after
swimming in a certain lake
Amoeba reproducing asexually
A single Amoeba
Paramecia.. Animal like protists
Paramecia conjugating = trading DNA
(similar to sexual reproduction )
Paramecia. 1 cell big, but notice the small
hairs called “cilia” covering each cell
Paramecium dividing
PLANT-LIKE PROTISTS ( Algae )
Euglena. A single celled protist… half
plant… half animal 
Euglena with a single flagellum visible
coming from the tip of each cell
Euglena with a red eyespot clearly visible.
Chloroplasts are also clearly visible
Euglena… common in our lakes and
ponds in Douglas County
KELP a plant-like protist. Kelp forests make rich
habitat in oceans for many other creatures
Gas filled bladders on kelp help to float
the “leaves” of this protist
Kelp forest. Kelp can grow 2 meters per
day = 6 feet! Very important producer
Kelp attach to the ocean bottom with
“holdfasts”
Sea urchins are animals which nibble through
then holdfasts of kelp…sometimes setting the
kelp adrift
Sea urchins on Kelp
Spirogyra… a plant like protist. We call
plant like protists… ALGAE
Spirogyra… common here in Alex. Not
a plant! A plant-like protist. ( algae )
Spirogyra algae
Volvox… a colony of green algae cells
common in Douglas County
Volvox. A plant like protists
Anabaena… a green alga
Anabaena… a plant like protist
( algae )
Water Net. A Green alga
?
Algae farms in the desert. Could these
protists produce enough oil to power our
vehicles?
Over 70% of earth’s oxygen is produced by algae.
Thank you little green photosynthetic algae dudes !!
.
Bubbles of oxygen in the sunlight as
photosynthesis happens
Single celled algae living inside of coral.= mutualism. The algae make
food for the coral animal during photosynthesis. What if you had algae
living in your skin?
Green alga inside coral animals
Sponges. These are animals which are green because
of an alga living inside.
Sloth fur is excellent algae habitit
Sloth with algae in fur
Red Tide. Caused by a plant-like
protist with red pigment ( red alga )
The organism which causes red-tide…
a red-alga which releases a nerve toxin
Red tide
Toxins released by the alga during a
red tide can kill millions of fish
Red tides can also kill manatees
Diatoms. Plant like protists with a
silica shell. Shell has many holes
A single diatom magnified hundreds of
times
Diatoms shells are added to
toothpaste, pool filters and road paint.
Close-up of a diatom shell showing the
holes in the shell.
White cliffs of Dover… Dover England. The
entire cliff is made of Diatom fossils
The anopheles mosquito.. Carries the
protist which causes malaria.
Anopheles mosquito injecting
plasmodium protozoans into human.
Bed nets help to prevent malaria
