6 kingdoms of Life 1. Plants 2. Animals 3. Fungi 4. Archaebacteria 5. Eubacteria 6. 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 AMOEBA CELL 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
