An example of a ciliophora
is the paramecium
Star shaped organelle:
Contractile vacuole
QuickTime™ and a
TIFF (Uncompressed) decompressor
are needed to see this picture.
Phylum:
Sarcomastigophora
• Move by flagella, most have 2 or more
• Some are parasitic
Phylum: Apicomplexa
All are parasites that cause disease in
most animal species
Plant-like Protists
• Domain: Eukarya
• Kingdom: Protista
• Phylum: there are seven:
– 1. Chlorophyta
– 2. Phaeophyta
– 3. Rhodophyta
– 4. Bacillariophyta (diatoms)
– 5. Dinoflagellata
– 6. Chrysophyta
– 7. Euglenophyta
Phylum: Chlorophyta
• Green algae
• Photosynthetic aquatic plant-like
organisms
• Two species live on land:
– 1. Protococcus - lives on tree trunks
– 2. Lichens - lives along with fungi on tree
trunks & rocks
Phylum: Phaeophyta
• Brown algae
• Seaweeds, kelps
• One species can grow to be 60 meters
long
• Only live in marine waters
Phylum: Rhodophyta
• Red algae
• The red pigment gathers a different
wavelength of light than the green
chlorophyll
• Red light penetrates water farther
than white light
• Red algae can live 270 meters
below the surface, far below other
algaes
Phylum: Bacillariophyta
• The diatoms
• Have a glassy shell that
have many commercial
uses
– Scrubbing powders like
Comet
– Toothpaste
• Are the most important
oxygen producers on
earth!!!
Phylum: Dinoflagellata
• Contain red pigments
• When conditions are right in the ocean
these can reproduce incredibly fast
• This explosion of dinoflagellates is
called an algal bloom
• The huge numbers of dinoflagellates in
the water cause it to turn a reddish
color
• This is called a red tide
• The toxins released by the huge
numbers of dinoflagellates cause large
fish kills
• Shellfish that live through a red tide
store the toxins that then can kill a
person who eats the shellfish later
Phylum: Chrysophyta
• Golden algae
Phylum: Euglenophyta
Oddballs - they have characteristics of
both animals and plants
They are classified as plant-like protists
because they are photosynthetic but they
also eat other protists (both autotrophic &
heterotrophic)
