KINGDOM PROTISTA
Protists- the hodge- podge group
Basics
Eukaryotic
 3 groups- animal like -Protozoans
plant like- Algae
fungi like- Slime molds
Evolved from a symbiotic relationship: 1 prokaryote
engulfed another (like a mitochondrial or
chloroplast like cell) ENDOSYMBIOSIS

Protozoans- animal like
HOW THEY
MOVE
PSEUDOPOD
FLAGELLA
CILIA
SPORES
(SPOROZOAN)
Example
Sarcodines
Amoeba
Zooflagellates
Giardia
Ciliates
Paramecium
Plasmodium
Environment
Salt and fresh
water
1.Streams
2. Gut of
termite
3. Parasite in
human DT
Ponds and
streams
Gut of
mosquito/
blood of
humans
Special
Structures
Contractile
vacuole- pumps
out excess
water
Help digest
cellulose
Ingest food
through oral
groove and
gullet
Macro and
micronucleus
Produce sporesneed
intermediate
host like
mosquito
Diseases
Amoebic
dysentery
Giardiasis
Malaria



Pseudopods stream in
different directions to
make amoeba move.
Single celled
Pseudopods surround
food and engulf it
Giardia



Can cause giardiasis.
Usually from
contaminated water.
Called backpackers
diarrhea
Paramecium


Use cilia to sweep
food into oral groove
and then digest in the
gullet.
Has 2 nuclei- I macro
and 1 micro
Plasmodium




Causes malaria
Lives in gut of
mosquito
Mosquito bites human
Injects some sporesthey germinate and
live in the blood
ALGAE-Plant like



Contain chlorophyll or other pigment
Can be unicellular, multicellular or colonial
7 types
Euglenophyte: Euglena




Unique because they
can do photosynthesis
and ingest
food(heterotrophic).
Has an EYESPOT which
helps detect light so it
can swim towards it to
photosynthesize
Has a flagella for
movement
Pellicle- thick outer
covering
Chrysophyte:Golden Algae



Many unicellular
Some colonial
Gold colored
chloroplast
Diatoms




Contain chlorophyll
Photosynthetic
Shell made of SILICAused for abrasives in
cleansers like
toothpaste
Also called
phytoplankton
Dinoflagellates




Cell wall contains
cellulose
Contain chlorophyll
Also have another
pigment called
carotenoid(orange color)
Cause Red Tide- due to
overgrowth in the ocean.
Produces a toxin that is
harmful to sea life and
humans
Red Algae






Phylum Rhodophyta
Multicellular
Marine sea weed
Has no roots, stems, or
leaves
Main structure called a
thallus
Has Chlorophyll a and
phycobilins that help
harvest light at deep
depths.
Brown Algae





Phylum Phaeophyta
Multicellular
Contain chlorophyll
and a brown pigmentFUROXANTHIN
Kelp
Have air bladders to
keep them afloat
Green Algae
Phylum Chlorophyta
 Most live in fresh
water
 Can be unicellular or
multicellular
Spyrogyra-multicellular
 Volvox is a colonial
green algae

Uses for Algae





Base of the food chain
Produce O
Sushi:nori
Smoothener in foods like ice cream and pudding
Industrial uses: plastics, waxes, deodorant, paint,
agar( material used to grow bacteria)
Fungi like – Slime Molds and Water
Molds


Live in moist, cool
environment
Watery moldsOomycota
