Kingdom Protista
The “Catchall” Kingdom
Three Divisions
 Animal-like-
Protozoans
 Plant-like- Algae
 Fungus-Like- slime molds
Protozoans


Means “first animal”- evolutionary term
Animal-like
Microscopic
Unicellular or colonial
Usually motile
Heterotrophic
Aquatic-ponds, lakes, moist soil, blood
Exchange gasses with environment
Reproduce asexually by fission
Protozoan Classification
 Classified
by locomotion
 Four Phylum




Sarcodina
Ciliaphora
Sporazoa
Zoomastigina
Phylum Sarcodina

Lack of body shape
 Flexible plasma membrane surrounding
cytoplasm
• ectoplasm- just inside membrane
• endoplasm- interior of animal

Ameboid movement by
pseudopods- “false foot”
• taxes- response to stimuli

Pseudopod also captures
food
Phylum Ciliaphora

Cilia- hairlike projections



Slipper shape




Propel the organism toward food
Move food toward organism
Pellicle- outer covering
Macronucleus
Micronucleus- functions during reproduction
Oral groove- food channel
Contactile vacuole- star shaped- release excess
water
Asexual reproduction as well as sexual
conjugation
Reproduction
 Asexual-binary
 Sexual-
fission- cell division
conjugation- along
oral groove
Sporazoans
 No
means of locomotion
 All parasites
Plasmodium falciparum- Malaria
 Carried
by Anopheles mosquito
Plasmodium Life cycle
Phylum Zoomastigina
(Flagellates)
 One
or more flagella
 Most live in ponds, lakes
 Some live in hosts as a
parasite
Paranema
Trypanosoma
 Carried by

tse-tse fly
Causes
African
sleeping
sickness
Giardia lamblia
 “hikers
disease”
 May be found in
crystal clear
streams
 Boil water for at
least 15 minutes
 “Beaver Fever”
Trichonympha
 Lives
in termite gut to
digest wood
 Symbiotic relationship
Algae
 Plant-Like
Protists
 Autotrophs
 Benefits

Base of Food
Chain
Perform 70% of
Earth’s photosynthesis
Multicellular- Classified by
Color
GREEN- spirogyra
RED
BROWN- kelp
Unicellular Algae- Euglenas
Freshwater
algae
Both
producer
and
consumer
Unicellular Algae- Diatoms



More oxygen
produced than from
any other organisms
Many uses

Other AlgaeDinoflagellates
Live
in
ocean
Some cause
Red Tide
Some are
bioluminescent
Red Tide
 Overgrowth
algae
 Produces
toxins that
may kill fish
and sicken
people
Karenia brevis (Dr. Karen Steidinger)
of
Bioluminescent
Dinoflagellates
 Glow
when
agitated
 Found in only
a few places
in the world
