Kingdom Protista
Protists
Draguesku Protists 0214

DIVERSITY OF PROTISTS
“Junk Drawer” of the kingdoms
very diverse (lots of different
organisms are included in this
kingdom)
range in size [unicellular to multicellular]
variety of reproductive and nutritional
strategies
Can be heterotroph or
Autotroph
1. Animal like
Ex: Protozoans
2. Plant like
3. Fungus like

ANIMAL LIKE PROTISTS
(AKA: PROTOZOANS)
Resemble animals
Unicellular
4 Phyla (plural for
phylum)
Based on movement
HOW DO WE
SEPARATE
THEM INTO
PHYLA????
It is based on
how the
organism
MOVES
Draguesku Protists 0214

1. PSEUDOPODS
PHYLUM SARCODINA
EXAMPLE:
PSEUDOPOD (FALSE FOOT)
CONTRACTILE VACUOLE
Collects and expels H2O (excess) out of the Cytoplasm and
out of the cell
Amoeba engulfing an organism
WWW.PHSCHOOL.COM WEB CODE: CEP 1031 To see the amoeba move.
AMOEBAS
NUCLEUS
CELL MEMBRANE
FOOD VACUOLE
Draguesku Protists 0214

2. Cilia (Phylum Ciliophora)
Example: Paramecium
Cilia used for
locomotion
Contractile vacuole expels excess H2O
Macronucleus (large)
Metabolic processes
Micronucleus (small)
Gullet
pellicle
Reproduction
Draguesku Protists 0214
6
Reproduction of Paramecium
Asexual BINARY FISSION
Sexual CONJUGATION
Paramecia join together and exchange genetic
material
3. Flagella (Phylum Zoomastigina)
Can have MORE than one flagella
Example: Trichomymphia
Termites have a flagellate (Trichonymphia) in their
gut to digest wood
Draguesku Protists 0214
7
This is an example of:
Relationship in which
at least one species benefits
Another kind of relationship:
Relationship in which BOTH
partners benefit
Giardia (another example of a flagellate)
Parasite
Found in fresh water causes “hikers disease”
SYMBIOSIS
Mutualism
Draguesku Protists 0214
8
4. Sporozoans (Phylum Sporozoa)
NO MOVEMENT
Transmitted by another animal
PARASITES
Example:
PLASMODIUM MALARIA
Transmitted by mosquitoes
Draguesku Protists 0214
9
AKA: ALGAE
Habitat
.Ponds, lakes, oceans
Autotrophic
Produce much of the O2 in the atmosphere through photosynthesis
Provide food for the aquatic food chains.
Important food source for other aquatic
organisms.
Size
Unicellular and multicellular
Color
Varies depending on pigment (chlorophyll)
Green, yellow, red, brown, orange
& black
PLANT LIKE PROTISTS
Draguesku Protists 0214
10
Diatoms
Most numerous
unicellular algae in the oceans.
Important source O2
Made up of Silica component of
glass
Make up Diatomaceous Earth
Used for scrubbing and pool filtering agents
Dinoflagellates
Unicellular
Stiff plates (suit of Armour)
2 flagella
Glow in the dark (bioluminescence)
Draguesku Protists 0214

**some are responsible for the RED TIDE
that kills fish
Red tide bioluminescence
Draguesku Protists 0214
12
Euglena
Euglenoids
Green, Unicellular
Autotrophs
Can be HETEROTROPH when no
sunlight available.
Eyespot is light sensitive
Red Algae
Multicellular seaweeds
Carrageenan & Agar
Used as food
In Asia; toasted Fresh
or dried
Used in food products and other
products
Example: Ice Cream; hair
conditioner; Nori (sushi)

Green Algae
Ancestors to first plants
Cell wall contains cellulose
Has Chlorophyll
Green Algae
Has this in
common with
first plants
Great-Great-

Grandma
We love
you
Grandma!!
Grandma
Green
Algae, you
started
everything!!
Draguesku Protists 0214
14
Green Algae:
Can live in colonies
Example: Volvox
Brown Algae
Commonly called Seaweed
Giant Kelp “forests”
Thrive in cool rocky water
Used for thickening (i.e. pudding)
Draguesku Protists 0214
15
The body contains:
Holdfasts for attachment
Blades and air bladders
that function in floatation
A stem like structure that
holds the blades is called
a stalk or stripe
FROND
BLADE
GAS
BLADDER
Also called
STIPE
Draguesku Protists 0214
16
FUNGUS LIKE PROTISTS
Heterotrophs
. Have Cell walls NO CHITIN
Use Spores to reproduce
Spores: Tiny cells that are able to
grow into a new organism
SLIME MOLDS
Live in forests and shady places on
decaying organisms
Draguesku Protists 0214
17
WATER MOLDS AND DOWNY MILDEWS
Grow as tiny threads that look like
“fuzz”
Water mold destroyed Irish Potato Crop
in 1845 & 1846.
Downey mildew Water mold
