2. Plant –like protists (Algae).
• All are producers….contain chlorophyll and can
make their own food.
• Many “phytoplankton” are a huge food source
for most aquatic animals
chloroplasts
• Freshwater algae
flagella
eyespot
Reproduction by fission
• Salt water algae
•Also called “brown algae”
• Photosynthetic protist that has a hard
outer covering that looks like
Shiny
glass-like material
______________________.
This
material does not decay, and is very
useful to other organisms’ diets.
This gritty
material is used
in cleaning
products.
(Brown seaweed)
Also called multi-cellular brown algae, and
can be eaten for food.
The only multi-cellular protist
Kelp forest off the coast of California
in Monterey bay
• Photosynthetic algae that are also
classified as red or brown algae.
“red tide”
Overpopulation can cause _______________
An overproduction of dinoflagellates can cause
“pollution” of water. This can effect the quality
of water and fish-life in that area. It is cause by
a sudden change in water temperature that
causes a dramatic increase in dinoflagellate
reproduction.
Other green algae
• Live in colonies
• known for their spiraling
chloroplasts and grow to
many centimeters long
3. Fungus-like protists
• Decomposers
• Grow on decaying
material, such as
logs and leaves on
the forest floor.
* Unlike fungus kingdom because of their cell wall
The Potato Famine in
Ireland in 1840’s was
caused by Phytophthora
infestans, fungus-like protist.
