Single cell protists that live in a _________: a hollow ball with each protist having a ____________ COLONY FLAGELLA SHAPES HARD TWO PART Photosynthetic algae with ________ flagella. Causes “_____________” with over population. TWO RED TIDE

16 1.One of the ______________ group of single- celled organisms that swim with _______________. 2.Most found in _____________ water. 3.Most are ___________________________ because they contain _________________ to produce their own food. 4.Have an _______________ to help them sense ______________ for __________________ LARGEST FLAGELLUM FRESH AUTOTROPHIC CHLOROPHYLL EYESPOT LIGHTPHOTOSYNTHESIS

17 FLAGELLA Single-celled plant-like protists that join together to form __________________ in the shape of a _____________________. Inside the parent colony, offspring are formed and known as“______________________” Individual cells have _______________ for mobility. COLONIES HOLLOW BALL DAUGHTER COLONIES DAUGHTER COLONY INDIVIDUAL CELLS FLAGELLUM OF INDIVIDUAL CELLS FLAGELLUM

18 Plant-like _____________ that are covered with __________________, _____________________. Diatoms produce about ____________ of all the _____________ we breathe. Used in ________________ products. ALGAE A TWO PART GLASS-LIKE SHELL HALF OXYGEN INDUSTRIAL

19 1.Give and example of each of the following: a single-celled, a colonial, and a multi-cellular plant-like protist. 2. Many plantlike protists, or algae, reproduce sexually when conditions are harsh. Why might this be beneficial for a species? 3. If a multi-cellular organism contains chlorophyll c but no silica, to which phylum does it likely belong? 4.Many biologists argue that the euglenoids should be classified as an animal-like protist rather than a plantlike protist. Explain.

20 1.Play an important role in the ______________________ as ________________. a.Recycle ________________ and _______________ back into the soil for __________________ use. 2.Difference between fungi and fungus-like protist is that fungus-like protist can __________________ during part of their life cycle while fungi ___________________________.

22 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 flagella chloroplasts Freshwater algae eyespot Reproduction by fission

23 Salt water algae Also called “brown algae” Photosynthetic protist that has a hard outer covering that looks like ______________________. This material does not decay, and is very useful to other organisms’ diets. This gritty material is used in cleaning products. Shiny glass-like material

24 Also called multi-cellular brown algae, and can be eaten for food. (Brown seaweed) The only multi-cellular protist Kelp forest off the coast of California in Monterey bay

25 Photosynthetic algae that are also classified as red or brown algae. 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. “red tide”

26 Other green algae Live in colonies known for their spiraling chloroplasts and grow to many centimeters long

27 3. Fungus-like protists Decomposers Grow on decaying material, such as logs and leaves on the forest floor. The Potato Famine in Ireland in 1840’s was caused by Phytophthora infestans, fungus-like protist. * Unlike fungus kingdom because of their cell wall

28 1.In what ways are slime molds and water molds similar to fungi? 2. Describe how slime molds help other organisms within an ecosystem obtain nutrients. 3. Make a three-column chat comparing plasmodial slime molds, cellular slime molds, and water molds. 4.Why doesn’t spraying water on slime molds work to destroy them?

29 PROTIST SUMMARY Protists have many different ___________________. Protists can be classified into ______________________, ______________________, and ______________________ phyla. All protists are ______________________ organisms, most of which are _________________________. Most animal-like protists can __________________, but all need to take in __________________. They can reproduce by _________________, _________________, and/or _________________. Some protists are plantlike. They produce _____________________ to make their own ____________________. As a bi-product, they produce _____________________ as well. These protists are considered the primary __________ ______________ for other organisms. Some will have a _________________________ to help them move about. The protists classified as fungus-like protest include _______________________. They are _______________________ and live off of ______________________.
